Project Template won't show. with an VSIX Project Template

Hello Pros,

I'm struggeling with the VSIX Project Template, i did the steps Microsoft told me (http://msdn.microsoft.com/en-us/library/dd885241(v=vs.100).aspx ), but the Template is not shown in the new Project Dialog (i have restarted Visual Studio).
Did someone get the same Issue.

Best Regards
Florian.

Please tell me if I wrote something technically wrong or I'm coding it not right and clean, I'm working on myself. Also please excuse me for my englisch, I'm an Austrian Nativespeaker (AUSTRIA no kangaroos). :)
