What version of Window do you have. You need Window Professional or above to get the compatibility option. If you have home Premium, it's not included
Compatibility mode is part of Home Premium - Pro and above have the Virtual XP mode which is different.
To run a program as administrator and in compatibilty mode ... right click on "Computer" select Open
Right click the drive with your installation disk and again select open
Locate the setup or installation program and right click on this. Select properties ..... a tabbed window then opens up select Compatibility and select your settings for the program.
Not sure of the solution but I think Falkyrn is the knowledgeable one on this
