So I installed 2.2 b11. After rebooting - which the installer prompts me to do, even though it immediately complains that it couldn't finish installation - I ended up with the following:

A crippled 2.1 SDK - all files gone.

No 2.2 SDK at all.

Then, a new installation of 2.2 SDK succeeds - this time without any rebooting. 2.1 SDK still gone.

But I want my 2.1 SDK back. It surely should be possible to have a variety of different SDK versions on the same machine, right? Well, if not, then it should.

So I try to install the 2.1 SDK. No luck, "you already have a newer version installed".

Ok, so I remove the 2.2 SDK. Then reinstall 2.1 SDK.

Then I reinstall 2.2 SDK. This time it succeeds...but 2.1 SDK is gone!


Please don't remove old SDKs! I just want to check out the new beta version!
