You needed to add "file:///" to the beginning of registry setting in Manifest key. Manifest entry is now "file:///[INSTALLDIR]ADDINNAME.vsto|vstolocal". Rebuilt setup project and reinstall addin. It will work.
Thank you for your suggestion. This is the exactly what I had in my original posting, and it definitely does not work the way I need it. After rebuilding the setup and installing the add-in the result is still (please observe the backslashes):
Thank you again for trying this out. I wouldn't be posting here if it was only for how VSTO add-in loading works.
For some intricate reason however I need to be able to use *only forward slashes* with the Manifest-value. So - once again - my problem here is strictly InstallShield related, and has very little to do with VSTO.
Say I wanted to write this entry to the registry:
file:///c:/foo/boo.txt
Now, I can't hardcode "c:/foo" because it's the user's choice at install time, neither can I use the more dynamic "[INSTALLDIR]" because this only gives me backslashes in Windows. So how would you go about it (without scripting or custom actions)?
