I've installed ExamDiff Pro 4.5 on Windows XP 64-bit an I tried to enable the Windows Explorer shell integration - but failed with the error message:
Could not load ExamDiff Pro SHell Extension (EDPShell.dll): %1 is not a valid Win32 application. (Error 193)

What is wrong ?

Try uninstalling/reinstalling ExamDiff Pro -- perhaps the DLL got corrupted somehow. If it doesn't help, try registering the DLL from the command line: open CMD, change directory to your EDP folder, then run this command:

Thanks for the quick help.
The registration in command line was successful an now it runs !
