Upgrade from MDT 2010 Update 1 Beta to MDT 2010 Update 1 RTW is not supported.

 

 

There was a bug in the MDT 2010 Update 1 Beta installer - it installs MDT as “per user” instead of “per machine”.

Because of this issue, if you install MDT 2010 Update 1 RTW on the same machine where MDT 2010 Update 1 Beta is installed,

upgrade is not done and you will see 2 entries (1 for MDT 2010 Update 1 Beta and other for MDT 2010 Update 1 RTW) in “Programs and Features”.

 

So if you have MDT 2010 Update 1 Beta installed, you need to uninstall Beta and then install MDT 2010 Update 1 RTW.
