Log in to Moonbase with your checkout email and download the installer shown there.

Please install the latest version. Use the installer in your Moonbase library, not an older file saved from an email.
Log in at <a href="https://rapidflow.moonbase.sh">rapidflow.moonbase.sh</a> with the email you used at checkout. Open the product and download the installer shown there. Every current Rapid Flow plugin is downloaded this same way.
When the installer finishes, quit your DAW completely and open it again. The new plug-in is picked up only when the DAW starts.
The email with the blue Log in button comes from licenses@mail.rapidflow.shop. In Gmail it usually sits in the Promotions tab, so open that tab first. It uses the same email as the order.
If the library looks empty, check that you are using the same email as the order. A different email opens an empty account. If you are on the right email and the product is still missing, reply to your order email and we will look it up with you.

Where do I download the latest version?

The 64-bit plugins go in C:\Program Files, not in Program Files (x86).

On Windows, the installer puts the VST3 plugins in C:\Program Files\Common Files\VST3.
Point the DAW&apos;s plug-in scan at that folder, or run a full rescan. Then quit the DAW and open it again.
They are not installed in Program Files (x86). That folder is for 32-bit software. If the DAW is only looking there, it will not see the plugins, even though the installer finished.
You do not need to choose a different folder during installation.

Where does Windows install the plugins?

What to do on Windows and on Mac when activation does not finish. Do not delete your Rapid Flow folders.

This has not been a fault in the plugin. Please follow the steps for your computer, then try activation once more.
<h2 id="windows">Windows</h2>
Use these checks when Let&apos;s Go does not open a browser, or when activation stops at Request timed out. Work from the top. Stop when a browser opens and you can sign in.
<h3 id="1-see-whether-windows-can-open-a-web-page-at-all">1. See whether Windows can open a web page at all</h3>
<ol>
<li>Press the Windows key and R together. Type https://example.com and press Enter. A browser should open.</li>
<li>Open Command Prompt, type <code>start https://example.com</code>, and press Enter.</li>
<li>Click a link in another program, such as your email.</li>
</ol>
If none of those open a browser, Windows is not handing pages to a browser. Continue with the next section. If they do open a browser, skip to section 3.
<h3 id="2-set-the-browser-for-web-links">2. Set the browser for web links</h3>
Choosing a default browser is not always enough. On Windows 10 or 11, open Settings, then Apps, then Default apps. Select your browser and set it for HTTP, HTTPS, .htm, and .html.
The plugin opens the page through those web-link types. If HTTP or HTTPS is not assigned, Let&apos;s Go can do nothing even when a saved HTML file still opens.
At the bottom of Default apps, choose Reset all default apps, then set your browser again. If a default-app fixer or a registry cleaner has been used, that reset is the fix. You do not need to edit the registry.
<h3 id="3-a-window-may-be-hidden-behind-the-daw">3. A window may be hidden behind the DAW</h3>
Windows sometimes asks &quot;How do you want to open this?&quot; behind the DAW, especially in full screen. After you click Let&apos;s Go, press Alt+Tab or minimize the DAW and look for that question.
Then close every Brave and Edge process in Task Manager, including the ones running in the background, and try Let&apos;s Go again. A browser that is already stuck open can swallow the request.
<h3 id="4-do-not-run-the-daw-as-administrator">4. Do not run the DAW as administrator</h3>
This is a common cause. Right-click the DAW shortcut or its .exe, open Properties, then Compatibility. If &quot;Run this program as an administrator&quot; is ticked, turn it off. Start the DAW normally and try again.
<h3 id="5-how-the-daw-hosts-the-plugin">5. How the DAW hosts the plugin</h3>
<ul>
<li>A sandbox or a bridge can block the browser. That includes Bitwig&apos;s sandbox, Reaper&apos;s &quot;run as separate process&quot; or bridging, a Studio One or Cubase 32-bit bridge, and jBridge. Load the plugin without the sandbox or the bridge and try again.</li>
<li>If you have another DAW, try Let&apos;s Go there.</li>
<li>Use the latest installer from your Moonbase library. On Windows, use the VST3.</li>
</ul>
<h3 id="6-security-software">6. Security software</h3>
Antivirus tools such as Bitdefender, Kaspersky, Norton, or Malwarebytes can block an audio program from opening a browser. Check the log or quarantine. You can turn that protection off for one test, then turn it back on.
In Windows Security, open Protection history. Also check Controlled folder access and Exploit protection for the DAW.
On a work computer, a company policy can block other programs from opening a browser.
<h3 id="7-try-another-windows-user">7. Try another Windows user</h3>
Create a new local Windows account and test the plugin there. If Let&apos;s Go works on that account, the problem is this Windows user, not the plugin.
<h3 id="8-if-you-want-to-see-what-windows-is-doing">8. If you want to see what Windows is doing</h3>
This step is optional. Process Monitor, from Microsoft Sysinternals, can watch the DAW while you click Let&apos;s Go. It shows whether the DAW tries to open a browser, and what error comes back. Event Viewer, under Windows Logs and then Application, shows errors from that same moment. The plugin may also write a log under %APPDATA% or Documents, in a Rapid Flow folder.
You can also open the license page yourself. Sign in at <a href="https://rapidflow.moonbase.sh">rapidflow.moonbase.sh</a> with the email you used at checkout.
If it still fails, reply and tell us whether the Windows+R check opened a browser.
<h2 id="mac-the-browser-says-the-license-worked-but-the-plugin-asks-again">Mac: the browser says the license worked, but the plugin asks again</h2>
The license file is damaged. The only known cause is moving from a cracked copy to a licensed copy. The file license.mb is exactly 100 bytes, which is not a normal license.
<ol>
<li>Quit the DAW.</li>
<li>In Finder, open your home folder, then Library, then Rapid Flow. If you do not see Library, click Go in the menu bar while holding the Option key.</li>
<li>Open the folder for the plugin that is failing.</li>
<li>Delete only the file license.mb.</li>
<li>Open the DAW and activate the plugin again.</li>
</ol>
Do not delete the Rapid Flow folder itself. It also holds your presets and, for Zensphere, the factory samples.
<h2 id="mac-the-license-does-not-stick-or-settings-and-presets-are-not-saved">Mac: the license does not stick, or settings and presets are not saved</h2>
The folders that store the license, the settings, and the presets are owned by another account, or they cannot be written. This only changes the owner and the permissions. It does not delete anything, and it is safe to run even if nothing is wrong.
<ol>
<li>Quit the DAW.</li>
<li>Open Terminal from Applications, then Utilities.</li>
<li>Paste the line below and press Return. Type your Mac password when asked. Nothing appears while you type it.</li>
</ol>
<pre><code>for d in ~/Library/&quot;Rapid Flow&quot; ~/Library/&quot;Application Support/Rapid Flow&quot;; do [ -e &quot;$d&quot; ] || continue; echo &quot;Fixing $d&quot;; sudo chown -R &quot;$USER&quot; &quot;$d&quot; &amp;&amp; sudo chflags -R nouchg &quot;$d&quot; &amp;&amp; sudo chmod -R -N &quot;$d&quot; &amp;&amp; sudo chmod -R u+rwX &quot;$d&quot;; done</code></pre>
Then paste this line. If it prints nothing, the folders are fixed:
<pre><code>find ~/Library/&quot;Rapid Flow&quot; ~/Library/&quot;Application Support/Rapid Flow&quot; $ ! -user &quot;$USER&quot; -o ! -perm -u+w -o -flags +uchg $ -print 2&gt;/dev/null</code></pre>
If it prints file paths, send that text to us. Then open the DAW and activate again.
Do not delete the Rapid Flow folders. They hold your presets and, for Zensphere, the factory samples.

Let's Go never opens a browser, or activation says Request timed out

Which current installers need AVX2, and which do not.

AVX2 is a feature of the processor. Some current Rapid Flow installers will not open on a computer that does not have it. The next version of every product will not need AVX2.
Here is what the current public installers need:
<ul>
<li>omniCLOCK needs AVX2</li>
<li>Sphere V3 needs AVX2</li>
<li>Zensphere V2 is not confirmed yet</li>
<li>miniGRID does not need AVX2</li>
<li>omniGRID does not need AVX2</li>
<li>True AB does not need AVX2</li>
<li>drumGRID does not need AVX2</li>
</ul>
If a plugin will not open and you think the processor might be the reason, reply with the product name and the computer you are using. We will confirm whether that installer needs AVX2.

What to try first, and how we can clear a stuck activation for you.

Please go through the other articles in <a href="https://rapid-flow-help.gorgias.help/en-US/articles/install-and-activation-457287">Install and activation</a> first, including the one for Request timed out and for a Mac license that does not stick.
If the plugin is still stuck on activation after those steps, reply to us. Tell us which product it is and the email on the order. We can clear that activation in your Moonbase account so you can activate it again.
Please wait for us to confirm before you buy the product a second time or try a different email. Clearing the activation is something we do on the account. The plugin cannot do it by itself, and we will not tell you it is already cleared until it is.

My plugin is stuck on the activation screen

The license email is from licenses@mail.rapidflow.shop. In Gmail, check Promotions first.

The license email comes from licenses@mail.rapidflow.shop. It has a blue Log in button.
In Gmail, open the Promotions tab first. That is where this email usually arrives. It does not go to the Spam folder. Search the inbox for Rapid Flow or Moonbase as well.
Open that email and use the blue Log in button. Sign in with the same email you used at checkout. Your downloads and the activation both live there:
<a href="https://rapidflow.moonbase.sh">rapidflow.moonbase.sh</a>
If Promotions and the inbox don&apos;t have the email, and Moonbase is empty when you use the checkout email, reply to us with that email and the order number. We&apos;ll look it up with you.

I can't find my license email

The FLOW Collective invite comes from Course Creator 360 and can land in spam.

The FLOW Collective invitation is not the same email as a plugin license. It comes from Course Creator 360, and the site in that email is rapid-flow.shop.
Create the account from that invitation first, before you try to log in on your own.
This particular email often lands in spam. Open the spam folder, find the invitation, and if Gmail asks, click Looks safe. The full message and the links appear after that.
If it is still missing after that, reply with the email you used at checkout and the order number. A person on the team will check the invitation.

The first activation needs internet. After that, omniCLOCK and miniGRID can run offline for up to 60 days.

omniCLOCK and miniGRID need an internet connection for the first activation. After that, each one can run offline for up to 60 days, and then it needs a short online check.
A computer that never goes online cannot stay activated. Take it online for that check when the plugin asks.
If a different Rapid Flow plugin asks you to connect, use the same idea: connect for the activation, then keep working. You do not need to be online for every session.

Do I have to be online to use the plugin?

Plugin sales are final because the download is instant. A person can review a genuine exception.

Sales of Rapid Flow plugins are final. The download is available straight away, so we can&apos;t offer a refund from this page.
The policy is here: <a href="https://www.rapidflow.shop/policies/refund-policy">Refund policy</a>
If something about the charge looks wrong, a duplicate payment for example, reply with the order email and what you were charged. A person on the team will review it. We can&apos;t promise a refund in advance.

Can I get a refund?

VAT is removed only for an EU business outside Portugal that adds a valid VAT ID at checkout.

Checkout includes VAT unless you are an EU business registered outside Portugal and you add a valid EU VAT ID on the checkout page.
A personal purchase, or a business in Portugal, is charged with VAT.
If the VAT ID was rejected or you need an invoice checked, reply with the order email and the VAT ID you used. A person will look at that. The checkout page is where the ID has to be added. We can&apos;t remove VAT after the order from this article.
