I installed TMG v8 on 64-bit Windows 7 a couple days ago. Later Windows Update said there was an optional update for AMYUNI Document Converter 400 from May 2010 (TMG v8 seems to install a 4.0.0.9 version from December 2009). After installing that update (4.0.1.2?), TMG v8 gave me an error when trying to do a Report - Save to Adobe PDF. The error was TerPrint2(a) Error Code Error finishing the page.
I did a System Restore to the Restore point created during the Windows Update process, and TMG v8 works again without error.
Is this the expected behavior (and did I miss some instructions about not being able to allow optional updates)?
