Photoshop 7.0 Won't Open on Windows 10 — 7 Tested Fixes

By the Photoshop 7.0 Hub editorial team · Updated May 17, 2026 · 11-minute read

Fix 1: Set Compatibility Mode (Solves 70% of Cases)

By far the single most common reason Photoshop 7.0 will not launch on Windows 10 or 11 is that the executable has not been set to run in compatibility mode. Photoshop 7.0 was written for Windows XP and its installer has a version-check routine that aborts on any newer Windows.

1. Open C:\Program Files\Adobe\Photoshop 7.0\ (or wherever you installed it).
2. Right-click Photoshop.exe → Properties.
3. Click the Compatibility tab.
4. Tick "Run this program in compatibility mode for:" and choose Windows XP (Service Pack 3).
5. Tick "Run this program as an administrator".
6. Apply → OK. Double-click Photoshop.exe.

If the application launches now, you are done. If it does not, continue to Fix 2.

Fix 2: Reset the Preferences File

Photoshop 7.0 stores its preferences (last window position, scratch disk location, custom colours, brush settings) in a file in %APPDATA%\Adobe\Photoshop\7.0\. If that file becomes corrupt — which can happen after a Windows update, an unexpected shutdown, or a failed first launch — Photoshop will crash before the splash screen even appears.

The fix takes ten seconds:

1. Close Photoshop completely (check Task Manager for any leftover Photoshop.exe processes).
2. Hold down Ctrl+Alt+Shift on the keyboard.
3. While still holding those three keys, double-click the Photoshop shortcut to launch.
4. A small dialog appears asking "Delete the Adobe Photoshop Settings file?". Click Yes.
5. Photoshop launches with factory-default preferences.

If it still does not launch, your preferences directory itself may be corrupt. Open File Explorer, paste %APPDATA%\Adobe\Photoshop\7.0\ into the address bar, and delete the entire 7.0 folder. Photoshop will recreate it on next launch.

Fix 3: Register MSCOMCTL.OCX

Several Photoshop 7.0 dialogs (Open, Save As, Image Size) depend on Microsoft's Visual Basic 6 common-controls runtime. Windows XP shipped with it pre-installed; Windows 10 and 11 do not. If you see the error "MSCOMCTL.OCX is missing or invalid" on launch, register it manually:

1. Download the Visual Basic 6.0 Common Controls package from the Microsoft Download Center (it is free and signed by Microsoft).
2. Extract the package and find MSCOMCTL.OCX.
3. Copy the file to C:\Windows\SysWOW64\ on 64-bit Windows, or C:\Windows\System32\ on 32-bit Windows.
4. Open Start, type cmd, right-click Command Prompt, choose Run as administrator.
5. Type: regsvr32 C:\Windows\SysWOW64\MSCOMCTL.OCX and press Enter.
6. You should see "DllRegisterServer in MSCOMCTL.OCX succeeded". Launch Photoshop.

Fix 4: Repair an Unavailable Scratch Disk

If Photoshop launches just past the splash screen and shows the error "Could not initialise Photoshop because some of your scratch disks are unavailable", your saved scratch-disk preference is pointing at a drive that no longer exists — typically because you removed a USB drive or changed drive letters. Photoshop refuses to continue without a writable scratch disk.

The fix:

1. Hold Ctrl+Alt while double-clicking the Photoshop shortcut.
2. A scratch-disk-selection dialog appears.
3. Set the first scratch disk to C: (or any drive letter that exists on your system).
4. Click OK.

If holding Ctrl+Alt does nothing, reset preferences with Fix 2 and Photoshop will ask you to pick a scratch disk fresh.

Fix 5: Resolve a Licence or Serial-Number Error

Symptom: Photoshop launches, displays the licence-agreement dialog, you click Accept, and Photoshop closes silently. Or it asks for a serial number every launch.

Cause: Photoshop cannot write its licence file because it does not have permission to C:\Documents and Settings\All Users\Application Data\Adobe\Photoshop\ (the Windows XP path), which on modern Windows has been redirected to C:\ProgramData\Adobe\Photoshop\.

Fix:

1. Right-click Photoshop.exe → Properties → Compatibility → tick Run as administrator.
2. Launch Photoshop. Enter the serial number. Accept the licence.
3. Close Photoshop, untick "Run as administrator" if you do not want UAC prompts every launch.

If the problem persists, your antivirus may be quarantining the licence file as soon as Photoshop writes it. Add C:\ProgramData\Adobe\ and the Photoshop install folder to your antivirus exclusion list, then re-enter the serial.

Fix 6: Crash on Splash Screen

Symptom: the splash screen appears for one or two seconds, then disappears with no error message.

This is almost always a font conflict. Photoshop 7.0 scans every font installed on the system at launch, and one corrupt or invalid font can crash the scan. Fix:

1. Boot into Safe Mode (hold Shift while clicking Restart from the Start menu; choose Troubleshoot → Advanced Options → Startup Settings → Safe Mode).
2. In Safe Mode, Windows loads only system fonts. Launch Photoshop. If it opens, the problem is a third-party font.
3. Reboot normally. Open C:\Windows\Fonts\.
4. Move recently installed fonts (anything you installed in the last few weeks) to a backup folder.
5. Re-launch Photoshop. If it opens, add fonts back in batches until you find the offending file.

Fix 7: Photoshop Opens but Workspace Is Off-Screen

Symptom: Photoshop is running (you can see its icon in the taskbar), but no window is visible — even right-click → Move does nothing.

The saved window position points to a monitor that no longer exists (you unplugged an external display). Fix:

1. Hold Shift while launching Photoshop — this resets the workspace layout without deleting all preferences.
2. If Shift alone does not help, hold Ctrl+Alt+Shift for a full preferences reset (Fix 2).

Still Not Working?

If you have worked through all seven fixes and Photoshop 7.0 still refuses to launch, the remaining options are:

• Uninstall and reinstall. Use Windows Settings → Apps → Adobe Photoshop 7.0 → Uninstall. Then delete %APPDATA%\Adobe\Photoshop\7.0\ and C:\ProgramData\Adobe\Photoshop\. Reinstall using our Windows 10 install guide.
• Run inside a Windows XP virtual machine using VirtualBox or VMware Workstation Player (both free for personal use). PS 7.0 in a VM runs flawlessly because the OS matches what the application was written for.
• Switch to a modern alternative. Photopea (browser, free, opens PSD files) or GIMP (desktop, free). See free alternatives.
