I have an application that was created using Visual Studio and packaged and installed using Installshield 2010. The application and installation have worked fine when installed on Windows XP and Windows 7 32-bit machines.
When trying to install the software on a Windows 7 64-bit machine the installation completes without error but when you try and run the application an error occurs refering to a log file that the app uses is read only. For some reason the folder that was created allows the user read-only access. This does not happen when the installation is run in a Windows 7 32-bit machine.
I can manually change the user permissions for the folder and that error goes away but then I get the a different error "requested registry access is not allowed" when the program launches. The app writes a value to the registry the first time it is run. This is happened on a couple different Windows 7 64 Bit machines.
It appears that this is all security issues but i am not sure why this only effects Windows 7 64-bit. Also, the user account that the software is being installed under is an administrator.
