I'm building a fairly simple installer with the LE version in Visual Studio. I and several others ran my installer several times during development, and everything was fine. At some point, it has started complaining that it does not have permission to create folders in Program Files, and that I should run as admin. Thing is, when running as admin, it still says the same thing! I've tried to revert all of the changes I had thought I had made since it started asking (this was to sig the exe, and change the name of the install folder), but it still says the same. Some info: Built on: Windows 7 Enterprise SP1 Visual Studio Pro 2013 InstallShield LE 2013 for VS Settings: Setup Launcher: Yes Required Execution Level: Invoker ALLUSERS="" Require Administrator Privileges=No Installing on: Windows 7 Enterprise SP1 (a different machine) User is member of 'administrator' group (though I don't want them to have to be...) Here is an extract from the installer log: MSI (s) (30:94) [03:43:35:895]: Executing op: ActionStart(Name=CreateFolders,Description=Creating folders,Template=Folder: [1]) Action 03:43:35: CreateFolders.
