I tried that fix and have to say:
COMPLETE DESASTER !!!
1) Installed "Setup.exe" as admin (W7, x64, german, all upfates applied), Firewall and Antivirus disabled;
2) Absolutely no user-interaction during installation, just a blinking cursor;
3) When finished, ALL PRINTERS in device-manager-printers were gone !!
Did this twice, same result. (Thanks to my Acronis-TI-Backup from the system-partition before testing)
This is hardly the solution, we have been waiting for so long. Maybe somoene else can test this "fix" and report, if the result is similar. A backup before doing so is highly recommended !!
In my case, it was a complete desaster, so let' s wait for the fix of the fix !
