I'm installing SQL2005 ent. on a active/passive win2003-sp1 2 node cluster.
Just before installation finishes I get an error:

Failed to install and configure assemblies C:\Program Files\Microsoft SQL
Server\90\NotificationServices\9.0.242\Bin\microsoft.sqlserver.notificationservices.dll
in the COM+ catalog.
Error: -2146233087 Error message: Unknown error 0x8013150 Error description:

Error pops up when Workstation components (last step) installation is
running and 'Removing backup files' is indicated in progress bar...
If I click 'Ignore', setup finishes a couple of minutes later with all
components installed. SQL seams to work OK, failover too.
Error states that some notification service component failed to install but
I'm not even trying to instal Notification services. I only selected
Database, integration and workstation components during setup.
Above link says that SQL can not verify if MSDTC is running. BOL says that
MSDTC should be present as a clustered resource. Is that realy necessary? In
SQL2000 there were no such error or requirement on win2003 cluster.
Can I leave installation in a condition as it is since everything seams to
work and application does not need MSDTC?
Funny thing is that I got the same error on second node when I was
installing Inegration and Workstation components on it since they are only
installed on first node during initial installation of SQL2005 on cluster.
It seams that Workstation components are the one that are causing the
error..

Anyone with the same problem?
