Not sure if this really matters or not. Even with the error on the install window, I was able to see the BazisLib project wizard in VS2008. Trying to create a project though failed.
I thought maybe the file was in use by something I had open (like Microsoft Document Explorer maybe). I closed everything and reinstalled. Same error.
After googling, I found out that file isn’t actually created until certain Visual Studio options are modified. I added an entry in options for an additional VC++ include dir. That created the VCComponents.dat file.
Running BazisLib install a 3rd time completed with no errors.
The project wizard still fails for me though, but I haven’t yet tried compiling that wizard from source (as I saw mentioned in response to another post). Just wanted to mention the VCComponents.dat thing though so it can be considered better in the installer and not cause confusion.
