We have an existing installjammer mpi setup that works on XP, however we're getting a lot of requests about problems with Win7 installs. One of the strange differences is the directory permissions. Our program needs to write to c:\windows\temp for some temporary files. As a test, I'm installing this as an administrative user. Installation appears to be successful, however when the program starts up and tries to access/write to this directory, it gets file errors because it's unable to write to it.
However, as soon as I visit the directory via File Explorer, I'm prompted by Windows:
"You don't currently have permission to access this folder. Click Continue to permanently get access to this folder."
Is it possible via IJ, to "preauthorize" this? Unless we tell our users to do this for every install, the software won't work correctly.
Are there other Win7 gotchas (migrating from XP installers?). I'm using Win7 Pro 64-bit.
