Hi there,
That happened to me already! It's pain in the "__

__" isn't it. This might work with your system.
Please launch Windows Explorer and go to Tools > Folder Options and on the View tab check "show hidden files and folders".
Empty contents of your Temp folder under C:\Windows\Temp. Clean up all files in C:\Documents and Settings\[UserName]\Local Settings\Temp folder.
Go to C:\Program Files\Ulead Systems and delete Photo Express folder.
Go to C:\Program Files\InstallShield Installation Information and delete the following folders if they are present: {1B5946C0-491A-11D4-ADD6-0010B53EC668}
Click Start > Run and then type "regedit", click OK.
Delete the following:
- Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\, please delete this entry:{1B5946C0-491A-11D4-ADD6-0010B53EC668} which corresponds to Ulead Photo Express. (if you cannot find the exact entry, click on each identity till you find one that corresponds to Ulead PhotoExpress).
- Under HKEY_CURRENT_USER\Software\Ulead Systems\, please delete Ulead Photo Express folder
- Under HKEY_LOCAL_MACHINE\Software\Ulead Systems\, please delete Ulead Photo Express folder
Close regedit and then restart your computer.
Reinstall Photo Express 4.0. Please restart your PC after installation.
Good luck
