I have at last got round to setting up a full installation VS 2010 Test and Lab Manager using the excellent notes from the Lab Management Team. Whist installing the build server portion I got a strange set of errors.
TF255425: An error occurred while installing the following Windows service: TFSBuildServiceHost.exe. For more information, open Event Viewer and review the application log.
TF255070: Configuring services for Team Foundation Build failed with the following exception: TF255425: An error occurred while installing the following Windows service: TFSBuildServiceHost.exe. For more information, open Event Viewer and review the application log..
Further investigation found the installer was claiming it could not find required files and so could not complete the install.
After a good deal of ineffective fiddling I cam to the conclusion the issue must be user access. I was using the trial Windows Server 2008 R2 vhds as the basis of my TFS server and test VMs, now these default to US region and keyboard. This had gotten on my nerves and I thought I had changed it to UK settings. However, I must have done it wrong as I had a UK keyboard in WinForm application but not in a Command Prompt. Once I made sure that my region, keyboard (and associated defaults) were all set to UK (and were working as expected in all locations) I tried the wizard again and it worked.
So it seems the issue was an incorrect password being passed to the installer. Some how the @ in Pass@word1 was being translated behind the scenes I guess to “ and causing the wizard to fail, though it always passed the verify stage of the wizard.
So the technical tip is to make sure the keyboard and region are right before you start, bit of a newbie error there!
