1) Do other modules work?
-NO, ALL files have same problem in my computer. I sent the file
to the other pc and I can open the configuration.
What I meant was do other modules in
CAESAR II work - like Input and Output? If these all work, but not the Configuration Module, I suspect a DLL registration problem.
Using Windows Explorer, browse to your \caesarii program folder and find the "netuserc2.bat" file. Double click this file, which will attempt to register all the DLLs in the \caesarii directory. See if that resolves the issue.
Please confirm that the software was "installed" on this computer, and not copied or transferred.
What is your Operating System?
