VSTS 2010 Beta 1 Installation Steps - A Personal Encounter

Update 2: Coming from some credible source, expect VSU 2010 RC in February 2010.

Update 1 : On 21 Oct 2009, VSU 2010 and TFS 2010 Beta 2 was publicly downloadable. The setup for Beta 2 is much smoother so this article may not be applicable to Beta 2. My environment (x86):

Server: Windows Server 2008 (Enterprise) running on VPC2007, IIS 7, SQL Server 2008, TFS2010, Windows SharePoint Service 3.0 SP2

Client: Windows 7, IE8, VSTS2010, Windows Media Encoder 9 Series

1. Install VSTS 2010 Beta 1
   
2. Install TFS 2010 Team Explorer
   
3. Install Windows Media Encoder & patch it
   This is to remove a bug in Microsoft Test & Lab Manager (MTLM) whereby video recording will crash the app. Check whether your computer has Security Update for Windows Media Encoder (KB954156) installed. If you do (I didn't), follow Step 1 else do Step 2 below
   
   
   • Go through the steps listed in http://support.microsoft.com/kb/929182
   • Install Windows Media Encoder 9 Series (here) and patch it (here)
   
   

Additional MTLM note:
In Beta 1, MTLM does not support cross-domain TFS credentials login. Since my server did not join the company’s domain, I’d have to open up MTLM from server rather from client. This is a known bug which I believe MS will fix in Beta 2.
[and rightly so it's fixed in Beta 2]
[I prefer Coded UI Test anyway]
