This is the problem with the permission systems on most newer platforms. It's either all or nothing; Run or don't run. If i find a good app for android where only a minimal feature requires some privacy intruding permission i can't install it at all even though i never want to use that feature. Same on Windows, either it's admin or it's not, there is no middle ground. Most installers ask for full super mega admin permission just to get write permisson in %programfiles%, what if i don't even want to install it there.

I think .NET and Java programs can be run until they encounter permission requirements and then prompt but i have rarely seen this feature used.

Obviously it's a usability tradeoff and the programmers of the app would also have to handle the permission rejection gracefully while running but i don't think that's too much to ask for.

That’s a different, and very valid, complaint. I agree with you that that feature should exist.
