Hi, thanks for posting!
This was something that was considered very carefully when the first NCrunch installers were being written. Unfortunately, I quickly realised that although it would save time for some people, it also had some serious drawbacks:
1. It makes the installer MUCH more difficult/expense to properly QA. Nothing is worse than an installer that fails, and a complex installer is certainly much more likely to fail.
2. It makes things very complicated in rare situations where people may choose to have different versions of NCrunch side-by-side. I would certainly take the point that not many people will do this, but the ones that do would have a hard time understanding why it couldn't be possible :)
Thanks for your feedback though. It's nice to know that I'm not the only person in this world that needs to develop with all 3 versions of VS at the same time!
Cheers,
Remco
