How to install the Windows Phone Developer Tools on Windows Server 2008
The Windows Phone Developer Tools are not officially supported on operating systems other than Windows Vista or Windows 7. In between the CTP and the CTP Refresh, a block was added to setup to prevent installing on Windows Server 2008 to help enforce this support limitation. I’ve heard from some folks who were using the original CTP on Windows Server 2008 who cannot move forward to the CTP Refresh or the final release because of this block.
There is a way you can work around the Windows Server 2008 setup block if needed. Please note that this is not officially supported, so if you try these steps, you are doing so at your own risk.
Download the Windows Phone Developer Tools web bootstrapper and save it to your hard drive
Extract the contents of the setup package by running vm_web.exe /x and choosing a path to extract to
Go to the folder you extracted to in step 2 and open the file baseline.dat in notepad
Look for the section named [gencomp7788]
Note - you have to change this exact section - this is the one that controls the OS version blocking behavior in Windows Phone Developer Tools setup.
Change the value InstallOnLHS from 1 to 0
Change the value InstallOnWin7Server from 1 to 0
Save and close baseline.dat
Run setup.exe /web from the folder you extracted to in step 2
Note - please make sure that you include the /web command line parameter in step 8. If you don't, setup will not attempt to download the packages it needs to install, and it will fail to install correctly as a result.
<update date="9/17/2010"> Added an emphasis on steps 4 and 8 - setup will fail if you don't pass in the /web switch when using these steps. Also updated the steps for the final RTW build of Windows Phone Developer Tools. </update>
