When upgrading to WFBS and WFBSA 6.x from previous versions of Trend Micro WFBS and CSM for SMB, I've had multiple times where the Worry-Free Remote Manager Agent install fails and gives the following pop-up error:
Unable to load Library C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\{43F8CF32-15B7-44DD-A01D-A3372DD2856E}\zlib1.dll.
If you run across this, Trend has a great KB that will walk you through doing a manual removal. If you keep the GUID in your Worry Free Remote Management Console, then you can do a copy and paste into the new install of the agent and you'll be set.
If you don't feel like clicking through to the KB, here's a copy of it as of 9/8/2010:
