Yesterday I was creating three virtual servers for a customer of me with the TFS 2010 Testcontroller and test agents installed on it. The virtual servers are all new Windows Server 2008 SP2 versions. The first thing that I had to do was (obviously) installing the TFS test controller software. So I started the ISO that the system administrator had mounted for me and started the setup. After that I clicked installing test controller software because that was needed on the first server. The setup said it would install the VC 10.0 Runtime for me and the test controller so I hit the next button. The installation started but after say 5 seconds the setup failed. I opened the setup log file and saw a weird error:
CMsiComponent::Install() expects the setup file for VC 10.0 Runtime (x86), but the file failed verification.
This was not clear for me what to do so I did a search with my favorite search engine. I saw a lot of post with a corrupted version of the Visual Studio 2010 ISO. But this was not the case because this was TFS software. So I downloaded the ISO myself again and extracted all the files. This gave me also the same error.
Then I remembered that I had this error one time before. It took me 2,5 hours of searching and trying before I remembered that… I downloaded Daemon Tools lite (mounting software) and mounted my new downloaded ISO on my new virutal DVD player. Started the setup again and now it installed within a minute. Very strange but you have to mount the ISO directly on the Windows Server 2008 server and not from a network share. I tried the solution on the other two servers (they where giving me the same error) and there the solution worked also instantly.
Hopefully I help someone with this problem or a related problem so your not searching 2,5 hours for a solution (a second time).
