Received the following error during the SP1 installation:

Some controls aren’t valid. Setup previously failed while performing the action “Install”. You can’t resume setup by performaing the action “BuildToBuildUpgrade”.

It seems as though the server thinks a previous installation operation never completed. An interrupted setup never occurred on this system, but whatever, that’s what it thinks.

My setup is Windows Server 2008 R2, Exchange 2010. To resolve this error and continue installation open up your registry and go to

• Open regedit
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14\MailboxRole
• The role could potentially whichever role your server thinks installation was interrupted during
• Delete the key named Action

I’ve read posts that mention the existence of a value for the Watermark key is the issue, however my testing showed that deleting the Action key resolves the issue.  It is in fact what the error specifically states is the problem. Not sure if that logic can be applied universally however.

I would have expected there to be no problems with most of them. I started out with a dinky little site that uses a small Microsoft Access Database.  This site uses a standard DSN to access the .mdb. I proceed to go to the Administrative Tools and open the ODBC Data Source Administrator window and add a new DSN for the .mdb and lo and behold I see the following nearly empty window:

<– This of course is no good! Where are all the other data drivers? Apparently all the regular ones we are used to seeing in 32bit Windows no longer exist as 64bit drivers.  The trick is to execute %windir%\SysWOW64\odbcad32.exe.

<– This will give you the ability to add the rest of the 32bit Data Sources such as Microsoft Access (.mdb).
