Failed to create instance if Software Execution Request Managerr. 0x80070005

Greetings,

   My task sequence gets nearly all the way through, installing all sorts of apps and then it hangs launching a particular app. On some machines it doesnt hang. When I look at smsts.log I have these lines repeating forever:

Failed to create instance if Software Execution Request Managerr. 0x80070005

Waiting for ccmexec process to start.

These two lines repeat every 5 seconds until I force the power off of the machine.

It appears that 80070005 sometimes is an access denied thing but that doesnt explain why %95 of the task sequence before this step works or why this step has no problem on other machines.

Any ideas?

Thanks

David Z
