Resolving MMC 3.0 errors when installing Exchange 12 CTP release
Published Mar 23 2006 10:41 AM 2,043 Views

As mentioned before - we now have CTP build of Exchange 12 those of you that have MSDN and TechNet subscriptions can install it.

 

One issue that seems to come up frequently for those of you that have tried installing this build is the following error at Setup:

 

"Exchange Server '12' requires Microsoft Management Console 3.0."

 

This happens even though the final (RTM), released version of MMC is installed on the system.

 

The problem here is that the CTP build of Exchange 12 setup actually needs a "RC1 refresh" build of MMC 3.0, and as this build is not found - the setup fails with the above error. E12 is looking for a registry key that is not there on the machine that has RTM version of MMC 3.0 installed. This issue is going to be fixed in later builds of Exchange 12 and will definitely not be there in final release version.

 

You can resolve this problem in 2 different ways:

 

1.    Download and install the RC1 refresh MMC release, see Microsoft Management Console 3.0 Pre-Release (RC1 Refresh).  

 

2.    If you would like to run the RTM version instead (as you already installed it) create the following empty registry key:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\MMC30Core

Seems like there's something missing in the Regkey:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftCurrentVersionUninstallMMC30Core

guess it's gone be "windows"?
like in:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstallMMC30Core

Microsoft’s Exchange 12 Beta arrived in my TechNet pack, and I had a box on which to install it. Why not? The Beta supports 32-bit hardware; production versions will not, according to the release notes. Installation was only a minor...

I still can't get this working.

Firstly, I added the registry key. I got the same error message.

Secondly, I installed Microsoft Management Console 3.0 Pre-Release (RC1 Refresh). I got the same error message.

Any help ???
