I have created a Setup.exe with InstallShield 2009 Express Version 15. The ALLUSERS setting is set to "1". A Computer adminstrator has installed the program. If the User has an Account Type as "Computer adminstrator" then there is no problem running the program. If the User has an Account Type as "Limited" then the user will get the following error message "Run time error 3051. Cannot open the file. It is already opened by another user or you need permission to view its data." I know that the file is not being used by another user. How do I set the permissions for this file.
