Excellent post and very helpful. I have a question regaring one element of it:
3. Click on the Compatibility tab. (See screenshot below)
NOTE: If the Compatiblity options are grayed out, then it is a 64 bit program and cannot be changed.
Why is it that you cannot change compatability options on a 64 bit program?
Is there any way around this?
The reason is that I have had to install the x86 version of Media Player Classic as opposed to the 64 bit version as I need to 'disable visual themes' and 'disable desktop composition' in order for my ATI Radeon 'theatre mode' to correctly launch the application in full screen on my second display.
Without disabling these options the application incorectly launches in a window on my second display.
As the compatability options were greyed-out when running the 64bit version of the application I had to install the x86 version instead
Does anyone know how to set these compatability options for 64bit applications?
