The program shuts down on Windows 7 depending on write permissions to folder where exe file is located. You should try to copy casplab*.exe file to folder you have a write permision. This is because casplab automaticly writes each measurement result to archive/cache file which is creaded in the same folder where casplab exe file is located.
One cache file is created per one launch of the application. Files are named _casp.res, _casp0.res, _casp1.res and so one.
