Quick answer (for advanced users)
Run the Adobe Creative Cloud Cleaner Tool in Safe Mode, then manually delete C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\ and HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\ leftover registry keys. Reboot, then install fresh.
Why this error happens
I know this error is infuriating — you're trying to install the Adobe Suite, you've uninstalled it, but it still says "This product is already installed." This tripped me up the first time too, especially when I was helping a design team switch from Photoshop CC 2018 to the new one. The real trigger here is a corrupted or incomplete previous installation. When you uninstall Adobe apps through the normal Windows uninstaller, it leaves behind registry entries, license files, and service-related folders. The Adobe installer checks for these remnants and assumes the product is still there, blocking the new setup. It's not a license server check — it's a local check against those stubborn leftovers. I've seen this on Windows 10 (version 22H2) and Windows 11 (23H2) with Adobe Suite 2023 and 2024.
Fix steps
- Run the Adobe Creative Cloud Cleaner Tool. Download it from Adobe's official site (it's a standalone .exe, around 2 MB). Run it as administrator. In the tool, select "Adobe Creative Cloud" and then hit "Clean." This removes all Adobe services, scheduled tasks, and app data. Let it finish and reboot.
- Manually delete leftover folders. After reboot, open File Explorer and go to
C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\. Delete everything inside. Don't worry — these are just temp files from the old installer. Also checkC:\Program Files\Adobe\for any empty folders left behind. - Wipe the registry keys. Open Regedit (type it in Start). Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\. Right-click the "Adobe" key and export it as a backup first (just in case). Then delete the entire "Adobe" key under WOW6432Node. Also checkHKEY_LOCAL_MACHINE\SOFTWARE\Adobe\(the 64-bit path) and delete that too if it exists. Don't touch anything underHKEY_CURRENT_USER\Software\Adobe\unless you're certain — that's for user preferences, not installation data. - Reboot again. Yes, again. This ensures the registry changes take effect and Windows clears any locked files.
- Install the Adobe Suite fresh. Download the installer from your Adobe account (Creative Cloud desktop app or direct download). Run as administrator. It should now proceed without the error.
Alternative fixes if the main one fails
If the above doesn't work, try these in order:
- Use the Adobe Uninstaller for individual products. Go to
C:\Program Files (x86)\Common Files\Adobe\AdobeGCClient\and runAdobeUninstall.exe. This targets specific apps like Photoshop or Illustrator. If it finds any remnants, it'll remove them. - Run a Windows System File Checker. Open Command Prompt as admin and type
sfc /scannow. Corrupted system files can sometimes interfere with Adobe installation — I've seen this on machines with pending Windows updates. - Disable your antivirus temporarily. Bitdefender and McAfee have been known to block Adobe's installer from writing registry keys, causing the error to reappear. Disable real-time protection, install, then re-enable.
- Use the Creative Cloud Desktop app's "Uninstall" feature. Sign in to the CC app, go to Apps, find your product, and click the three dots > Uninstall. This sometimes catches what the standalone uninstaller misses.
Prevention tip
Don't rely on the Windows uninstaller to remove Adobe products. Always use the Creative Cloud desktop app's uninstall option, or the Adobe Cleaner Tool. I learned this the hard way after spending two hours on a client's machine. Also, if you're switching from an older suite (like CS6) to a newer one, use the Cleaner Tool before even starting the new installation — it saves a ton of headaches. And keep your Windows up to date: Adobe's installer often checks for .NET Framework or Visual C++ redistributables, and missing updates can cause this error to pop up even with a clean system.
