Our IT security department mandated that we apply KB937832 and KB934525 to our
MOSS 2007 X64 environment. I wanted to wait until SP1 but lost the battle.

Applying the patches was done and the last step was to run the products and
technologies wizard. Well unfortunately, regardless of which front-end webserver
we run it on, it errors out around step 8 and has broken our website.

The wizard doesnt seem to allow us to rollback the upgrade. Instead, it asks us
to resolve the problem and rerun the wizard. Great.

I have tried rebooting, and googling to no avail. Does anyone know what might be
causing this?
