I've got 2 freshly installed ACS 4.2 for Windows servers and I need to apply the latest patch rollup before I build the configurations. I stopped the ACS services and ran Acs-220.127.116.11.15-SW.exe to install the patches. The application begins running fine but fails on upgrading the database and then none of the ACS services would start. I was able to restore the files from the backup that runs with the patch utility and get ACS functioning again. What am I missing - does the patch rollup require any specific Microsoft Patches to be installed or something like that?
