I have a 2008 R2 domain controller which I use for Group Policy. Up until now I have been using the ADM files which I see now have been replaced with the ADMX which were available before. But when I went to download the template for office 2013 only the admx were available. When I tried to add it using the Add/Remove Templates, they weren't available since I think that is only for ADM type.
I have been reasearching and all the sites say to copy the admx file to C:\Windows\PolicyDefinitions or to create a PolicyDefinitions folder in the sysvol for use as a central store. I tried both and I still get an error parsing message which everyone talks about but says copying to PolicyDefinitions is the solution.
