Visual studio .net setup project and registry values?

[johnny]

How can i add a programs installation path in the registry keys in a setup
project?
since i dont know where the user installed the program i need to set a
registry key
containgin a string value of the path the user chose for the program...

I cant find any real documentation for this anywhere...
so if anyone knows how to do it or know where i can find documentation about
it please let me know.

Thanks

Could your application record what directory path it started in and then
save that
value to a key the first time it runs?
