Hi alx,

Have you changed the name or guid of an already compiled (thus registered) package and tried to recompile it? I can repro the issue when doing the previous.

What is happening here is the templates will already be registered for another package, from the exact same location, and that won't work.

You could try the following workaround:
 
1 - Open regedit
2 - Open the HKLM\SOFTWARE\Microsoft\VisualStudio\8.0\Packages\{77d93a80-73fc-40f8-87db-acd3482964b2}\Templates
3 - Find the key that contains the guidance package you renamed (or the guid). There's an entry PackageName that will help you find out which one is the offending key. You will also see all the templates registered so you will be able to infer it by the templates location.
4 - Delete the key
5 - Restart VS

Hope this helps,

Worked like a charm. Thank You !

What I have done ? Hard to say.

I have generated a package, and I have started to modify the source files, trying to understand the structure. I have copied some source files, renamed them, modified them, compiled ...

After the error ocurred I was not able to open a Guidance package. I will try to reproduce-it now.

My goal was to understand how is supposed to be used.
I can see that this has a huge potential and I want to convert (and expand) my CodeSmith templates with this package.

What puzzles me right now is that I have searched the registry   ... with no result.

Yes: search whole string was checked !   Damn !
