What Triggers the “Sorry, this Adobe app is not available” Error?

As a creative professional, you know the sinking feeling when you try launching Photoshop or Premiere Pro and get slammed with the dreaded "Sorry, this Adobe app is not available" error. Your heart skips a beat as your workflow grinds to a halt.

Not to worry my friend, this is a common licensing hiccup that we can definitely troubleshoot. As an Adobe power user myself, I‘ve been down this frustrating road before too.

In this epic walkthrough, I‘ll be there with you step-by-step to uncover what‘s causing the error and get your Adobe apps back up and running. Think of me as your virtual support technician!

First I‘ll explain exactly what triggers this message so you understand what‘s failing under the hood. Then we‘ll methodically work through several fixes, from easy stuff you can do in seconds to advanced troubleshooting techniques.

By the end, you‘ll have the solutions to bypass the error and get back to editing, designing, and creating with no more annoying interruptions. Let‘s do this!

Before we actually start fixing things, it helps to know what causes this error in the first place, right? When you try launching a Creative Cloud app and see this message, here‘s what‘s happening behind the scenes:

The Adobe app needs to phone home to Adobe‘s licensing server to verify your subscription status and identity. It‘s checking that you‘re still an active member with a legit license to use Photoshop, Illustrator, Premiere Pro, etc.

When the app can‘t reach the licensing server for any reason, it fails to authenticate your access. As a piracy prevention measure, it displays the “Sorry, this app is not available” error to block you from using it.

So in nearly all cases, the root causes boil down to:

Network connection issues preventing the app from phoning home
Problems with the Creative Cloud desktop app that handles the licensing
Invalid or expired Adobe ID login credentials
Server issues on Adobe‘s end

As long as one of those factors is broken, you‘ll see the error when opening your Adobe apps.

The good news is that most of those causes can be fixed yourself without having to sit on hold for Adobe support!

Now let‘s walk through some top troubleshooting steps to get to the bottom of what‘s failing for you and how to resolve it. I‘ll provide a range of techniques from quick and easy to more advanced fixes.

Quick Fixes

Let‘s start with a couple quick things you can verify that take just seconds.

Ensure You Have an Internet Connection

First and foremost, the Adobe app obviously needs an internet connection to reach the licensing server. Open your web browser and try loading some websites:

If pages load fine, you‘re good on this front.
If pages fail to load, close browser, disconnect and reconnect to WiFi, reset modem/router if needed.
Try switching WiFi networks or use wired ethernet connection if possible.

Once you‘re back online, attempt to launch the Adobe app again before moving on to other fixes.

Update the Creative Cloud Desktop App

The Creative Cloud desktop app that runs in the background handles the licensing process for all your Adobe apps.

Go open the Creative Cloud desktop app and click on your profile picture, then choose “Check for App Updates”. Install any available updates, then restart the Creative Cloud desktop app.

Now try again to launch your Adobe app. Occasionally, an outdated CC desktop app causes issues communicating with the licensing server. Updating it can resolve things.

Okay, those were some quick preliminary checks that sometimes do the trick. But if you‘re still seeing the error, don‘t worry – we‘ll dive into some deeper troubleshooting next.

Reset Creative Cloud Desktop App and Licenses

If quick fixes don‘t work, our next suspects are the Creative Cloud desktop app and any stale Adobe licenses/certs stuck on your computer. Let‘s refresh everything.

Here are the steps I‘d recommend to completely reset the CC desktop app and your licensing:

Launch Creative Cloud desktop app
Click your profile picture ➜ Sign Out
Close Creative Cloud desktop app
Browse to C:\ProgramData folder
Delete Adobe and Adobe Creative Cloud folders
Press Windows Key + R to open Run dialog
Type “CMD” and press Enter
Type in the command:
```
REG DELETE HKLM\SOFTWARE\Adobe /f 
```
Press y and Enter
Restart computer
Re-install latest Creative Cloud desktop app
Sign into your Adobe ID again

This clears out any corrupted data related to the Adobe licensing and CC app registry entries. Reinstalling gives you a fresh start.

Now when you open your Adobe apps, tell me if it triggers the licensing check and authentication again as if opening for the first time. That‘s a good sign it worked!

Adjust Your Firewall and Anti-Virus Software

Another suspect that often interferes with licensing processes is third-party firewall and anti-virus security tools. They may be blocking the Adobe apps from phoning home.

Here are a few things you can try to rule out conflicts:

Temporarily Disable Firewall and Anti-Virus

Open Settings > Update & Security > Windows Security
Turn Off Real-time protection
Turn Off Firewall

This prevents them from blocking Adobe app traffic. Test if your app launches normally again. If so, re-enable protection and move on to next steps.

Allow Adobe Apps in Firewall/Anti-Virus

Open your security tool (Firewall app or Anti-Virus)
Find the option to create exceptions or exclusions
Exclude the entire Adobe folder, typically C:\Program Files\Adobe
Also exclude specifically the Creative Cloud desktop app folder

This prevents them from scanning or blocking Adobe‘s processes. Much cleaner than fully disabling security.

Reset Network/Internet Settings

Finally, you can reset your network settings as a catch-all troubleshooting step:

Open Command Prompt as Administrator
Type netsh winsock reset and press Enter
Restart your computer
Then run netsh int ip reset and restart again

This wipes all network/DNS settings and caches and renews them cleanly. Worth a shot if all else fails!

Advanced Troubleshooting Options

If you‘ve made it this far but are still seeing the error, we‘ll have to break out some more advanced techniques. Don‘t worry though, I‘ll walk you through them!

Modify Hosts File to Block Adobe Servers

The Windows hosts file acts as an override for DNS lookups. We can block connections to Adobe‘s licensing servers by adding entries.

Here are the steps to modify your systems‘ hosts file:

Right-click Notepad and Open as Administrator
Go to File > Open and navigate to:
```
 C:\Windows\System32\drivers\etc
```
Open the "hosts" file

Add the following entries to the bottom:

 127.0.0.1 activate.adobe.com
 127.0.0.1 practivate.adobe.com 
 127.0.0.1 ereg.adobe.com
 127.0.0.1 activate.wip.adobe.com 
 # etc (add any other licensing server domains)

Save changes and close Notepad
Restart computer for changes to take effect

Now when your Adobe app tries connecting to those domains for licensing, it will fail gracefully instead of showing the error.

Downside is you need to manually revert these changes later by removing the entries once Adobe‘s servers are stable again. But this allows you to work in the meantime!

Use Firewall App Rules to Block Adobe Apps

Alternatively, you can use Windows Firewall to block the outbound connections of just the Adobe apps.

Here are the steps to create an outbound rule blocking Photoshop specifically:

Open Windows Defender Firewall > Advanced Settings
Click Outbound Rules on left panel
Click New Rule on right panel
Select Program as rule type
Click Browse and locate Photoshop.exe file, usually here:
```
 C:\Program Files\Adobe\Photoshop CC 2019\Photoshop.exe
```
Click Next, select Block the Connection, and click Next again
Give the rule a name like "Block Photoshop Outbound”
Finish creating the new rule

Now Photoshop is blocked from phoning home, but your other apps and network access work normally.

Repeat these steps to create targeted rules for each misbehaving Adobe app. This isolates them so licensing fails gracefully while everything else works.

Nuclear Options – Fresh Install Windows or Adobe Apps

Alright, real talk here friend. If you‘ve tried all of the above solutions exhaustively but are still plagued by the error, we‘re down to nuclear options:

Fresh Install Windows

As a last resort, you can backup your data and perform a completely clean reinstall of Windows from scratch. This wipes all settings/programs and starts you off fresh.

Follow Microsoft‘s instructions to reinstall or restore Windows 10.

This removes any corrupted files, registry issues, or software conflicts that may be irreparable otherwise. You‘ll have to reinstall programs afterwards.

Uninstall/Reinstall Adobe Apps

Slightly less extreme, you can attempt fully uninstalling your Adobe apps with the Creative Cloud Cleaner Tool.

Then grab fresh installers for your apps from the Creative Cloud desktop app and install them cleanly again. This wipes any licensing glitches.

If neither of those nuclear options fix things, there‘s likely an account-specific issue on Adobe‘s servers tied to your Adobe ID that requires contacting their support team.

But hopefully it doesn‘t come to that point, as the other troubleshooting steps should resolve the error in nearly all cases! Let me know if any in particular do end up working for you.

Prevent Issues in the Future

After finally quashing that nasty error, here are a couple pro tips to avoid this headache down the road:

Always Keep Creative Cloud Desktop App Updated

Be vigilant about regularly checking and installing updates for the CC desktop app whenever you‘re notified. Keeping this up-to-date prevents lots of issues.

Use a Timeout or Pause Feature

Some firewall or security tools have a “timeout” feature that pauses protection for X minutes to avoid conflicts. Use this when installing/updating Adobe apps.

Contact Support If Problems Persist

Don’t hesitate to contact Adobe support for troubleshooting help or re-activation of your license if needed. They can investigate issues on Adobe‘s end:

Phone: 1-800-833-6687
