A network user is having problems running an engineering program. The engineering program "StormNET" runs complicated hydraulic calculations. The user is a typical network user and is not able to install any additional software. When the software tries to run a complicated calculation it produces and error about a file access but it does not tell me any more information about the file. I tried giving the user write access to folder c:\program files\stormnet but I am still getting an error.
What can I do to track down what the program needs write access to be able to complete the calculation?
The user is running Windows 7 64bit. It used to run under Windows XP.
