Using 32bit Backup exec GRT to backup 64bit Exchange 2007

I spent way to much time(again) trying to figure out what was wrong when my GRT backups just before completion it kept failing with 'E00084AF - The directory or file was not found, or could not be accessed.', by clicking the attaced link in the error message I was able to learn that this problem was caused by the advanced open filesystem trying to read/write something.

That turned out to be not entirely true, after some debug log parsing I was able to find that the ese.dll which BE uses to mount the database was of course a 64bit version and not 32 as my OS where BE was installed. At that point google told me to install the 32bit management console on the BE media server, since the 32bit version is not included on the 64bit media you need to go to http://support.microsoft.com/kb/555841 and download the eval package of 32bit Exchange 2007.
After a successful installation of the 32bit management console on my BE media server GRT backups works just fine :)
