MME on Windows 7 Ultimate


Hello. I'm trying to use a add-in that I developed (based on your MME) on Windows 7 and even with VS 2008 running as administrator and I checked add-in manager if the add-in is active and it is, and I also checked the vs 2008 in tools > add-in manager, and the mme is there and active, but my custom context menu won't show.. I have a filter for only xsl and xslt files.
Please can you tell me what's wrong? Thank you
