CRM Dynamics 2011 silent install issue.

Hello,

I'm trying to deploy CRM Dynamics 2011 on a Windows7 32bit machine, using SCCM 2007.

The commandline used is:

"SetupClient.exe" /config "Default_Client_Config.xml" REBOOT=ReallySuppress ALLOWRUN=1 INSTALLLEVEL=3 /q /l "C:\Windows\System32\CCM\Logs\\MS Dynamics CRM Outlook Client_Install.log"

On some machines the installation routine fails unexpected, according to the log file:

As you can see, the log is rather short and is not giving any reason for the failure. I really don't know what's the issue there.

Any hint is greatly appreciated.

Cheers
