Unable to install MSMQ : Error 0x8004e001 Triggers transactional component could not be registered in COM+


We are unable to install MSMQ due to error: Triggers transactional component could not be registered in COM+. Error Code: 0x8004e001

Since the error message talks about the transactions, we checked if the MSDTC service is running fine. It was not and infact we were not able to start it. When we try to start DTC service we get the error :

Reinstalled MSDTC service using the commands :

msdtc -uninstall
msdtc -install
msdtc -resetlog

Tried to start DTC service, we got the error :

Ran the command "msdtc -uninstall". Checked the registry key HKCR\CID to see if it is getting removed (msdtc -uninstall command removes the HKCR\CID key from the registry). It is not and infact there are more than 10 entries under that. Ideally we should have only 4 GUID entries under HKCR\CID.

We manually deleted the CID key. Ran the command "msdtc -install". DTC installed successfully and came up fine.
Ran the wizard to install MSMQ : SUCCESSFUL.
