In Windows 7, run program in compatibility mode is greyed out
In Windows 7, compatibility mode is used to run a program that is written for a previous version of Windows to run on Windows 7. I tried to install device drivers from Windows Vista on a Windows 7 machine. To install the drivers in compatibility mode, I had to right click on installation file, then choose Properties. In Properties window, there is a tab – ‘Compatibility’. It contains Compatibility mode, where we can chose that the program may run in compatibility mode for previous version of Windows. The following figure illustrates this:
This option is greyed with me, I can’t select from the drop-down list. I used the following procedure to fix it.
- Type ‘regedit’ in command window, so that we get registry editor.
- Goto this registry entry: HKEY_LOCAL_MACHINE->SOFTWARE->Microsoft->Windows NT->CurrentVersion->AppCompatFlags->Layers
- Delete this entry from registry, but take a registry backup before you do so.
- Restart windows.
Note: Make any change in registry at your own risk.
