In the last post I talked about a first look at Microsoft’s MDT 2010 Beta 2.

My inplace upgrade from Beta 1 “apeared” to be successful. However when I went to update the deployment share, I received the following error:

Update Deployment Share - Failed

This appears to be caused by a directory structure change in the WAIK between Beta and RC. Uninstalling WAIK, and resinstalling with the RC version will resolve this, but which version is the RC version? The WAIK RC is available from here as per Michael’s recent post

I have two ISO’s that I’ve downloaded recently from Microsoft:

en_windows_automated_installation_kit_x86_x64_ia64_dvd_349519.iso
KB3AIK_EN.iso

So according to the filename on the link on Michael’s blog I should be using KB3AIK_EN.iso. Except that this is the one that I did install when I built the server for MDT Beta 1.

Looking at the readme.htm in both ISO’s provides no clue either as neither are clearly marked as Beta or RC. Using Orca from the MSI SDK 4.5 I took a look at the ProductVersion and ProductName from the Property Table in the wAIKAMD64.msi. The values were the same for both:

ProductVersion = 2.0.0.0
ProductName = Windows Automated Installation Kit

In the end the only way I able to differenciate them was by the PackageCode in the Summary Information Stream:

Beta = {7FB35EC9-03A9-49AF-B0A1-81BDBA3949F5}
RC = {3BD5A1BF-F520-4BAA-9C7E-FAA12EF37AAF}

Restarting the MDT 2010 Beta 2 Workbench after the correct version of WAIK is installed, caused the following prompt:

Follow the steps as described to resolve the issue.

I don’t know how the filenames got reversed because I’m pretty sure I didn’t rename either of the WAIK ISO’s, but it provided for an entertaining half hour!
