Adobe 'Could not complete your request due to a program error' fix

This error shows up when you try to open a file, export, or even just use a tool in Photoshop or Illustrator. I see it most often when someone opens a PSD they downloaded from a client or imported from an old version. The exact message says: "Could not complete your request due to a program error."

It can also hit after you update Creative Cloud or install a new font. No crash log, no real clue what broke. Just that red box.

Root cause

The root cause is almost always one of three things:

• Corrupt file – the file you’re opening has bad data. Maybe it was saved with a buggy plugin or transferred via a bad USB.
• Corrupt preferences – Photoshop or Illustrator stores settings in a preferences file. Over time that file gets corrupted, especially after updates.
• Plugin conflict – third-party plugins (like Luminar, Topaz, or old actions) don’t always play nice after an update.

Less common but real: a corrupt font or a GPU driver that’s out of date. But start with the top three.

Fix 1: Reset preferences

This is the fastest fix that works in 70% of cases.

1. Close Photoshop or Illustrator completely.
2. Hold down Ctrl + Alt + Shift (Windows) or Cmd + Option + Shift (Mac) and start the application.
3. Keep holding until you see a pop-up asking if you want to delete the preferences file. You should see this after about 5 seconds.
4. Click Yes.

After clicking Yes, the app will launch with fresh preferences. Try opening the file again. If it works, great. But you’ll lose custom keyboard shortcuts and workspace settings. You’ll need to set those up again manually.

Fix 2: Disable GPU acceleration

If resetting preferences didn’t help, the GPU might be the problem. Photoshop sometimes craps out on older or unsupported graphics cards.

1. Open Photoshop.
2. Go to Edit > Preferences > Performance.
3. Uncheck the box that says Use Graphics Processor.
4. Click OK.

After clicking OK, restart Photoshop completely. Then try the action that triggered the error. If the error goes away, you’ll need to update your GPU driver or disable GPU for that specific task. I leave it off on machines with integrated Intel graphics.

Fix 3: Clear font cache

A corrupt font cache can cause this error when you’re working with text layers. This is common if you just installed a new font or updated your OS.

1. Close all Adobe apps.
2. On Windows: open File Explorer and go to C:\Users\[your username]\AppData\Roaming\Adobe\Adobe Photoshop [version]\Adobe Font Cache. Delete everything inside that folder.
3. On Mac: open Finder, press Cmd + Shift + G, type ~/Library/Caches/Adobe/Font Cache and delete the contents.
4. Empty the trash or Recycle Bin.
5. Restart your computer.

After restart, open Photoshop and try again. The font cache rebuilds automatically. If the error was font-related, it’s gone now.

Fix 4: Remove problem plugins

Third-party plugins are often the real culprit. I see this with old Topaz filters or unsupported actions from creative market.

1. Close all Adobe apps.
2. Go to the plugin folder:
   Windows: C:\Program Files\Adobe\Adobe Photoshop [version]\Plug-ins
   Mac: /Applications/Adobe Photoshop [version]/Plug-ins
3. Move all third-party plugin folders to your desktop. Don’t delete them yet.
4. Open Photoshop.

If the error goes away, you know one of those plugins is the problem. Reintroduce them one at a time, restarting Photoshop after each one. When the error comes back, you found the bad plugin. Delete it or check for an update.

Fix 5: Open the file in a different way

Sometimes the file itself is corrupt. But you can salvage the content.

1. Open Photoshop.
2. Go to File > Open.
3. Select the problem file, but instead of clicking Open, click the dropdown next to Open (if available) and choose Open as.
4. Try Photoshop Raw or Generic EPS format. You’ll lose layers but get the image data.

If that fails, try importing into a new document:

1. Create a new blank document in Photoshop (say 1920×1080 pixels).
2. Go to File > Place Embedded.
3. Select the corrupt file. Photoshop will try to place it as a smart object.

After placing, you might see a blank layer or a partial render. Save as a new PSD immediately.

What to check if it still fails

If none of these steps fixed it, here’s the short list of things to check:

• Update your graphics driver – go to your GPU maker’s site (NVIDIA, AMD, Intel) and get the latest driver. Don’t rely on Windows Update.
• Run Creative Cloud Cleaner Tool – Adobe has a free tool that removes leftover files from failed updates. Search for “Adobe Creative Cloud Cleaner Tool” and run it.
• Check for antivirus interference – some antivirus software blocks Adobe from writing temp files. Try disabling it temporarily.
• Send the file to a colleague – if only one file triggers the error, ask someone else to open it. If they can, your installation is the problem, not the file.

If you’re still stuck after all this, a clean reinstall of the Adobe app usually resolves it. Uninstall from the Creative Cloud desktop app, restart, then reinstall. But try the steps above first. Nine times out of ten, resetting preferences or removing one bad plugin fixes it.
