Same problem here.
Win7 64-bit. Original full-version purchase: PowerDVD 10 Ultra. Subsequent purchase: PowerDVD 11 Ultra. Previous patch applied: to build 1719 (early 6/2011).
I still can't use this program without it disabling Windows Aero, either. And I still have difficulty getting it to work with my sound card. I was hoping this patch might fix that.
I FULLY ENDORSE the comments from CRAIG R and STEPHEN J: the Cyberlink upgrade installer policy is a nightmare. We should not have to reinstall every previous version whenever we run into trouble, or buy a new computer. And PowerDVD 11 ultra upgrade leaves thousands of no-longer-used values in the Windows Registry when it 'uninstalls' version 10.
Even Adobe Creative Suite, a far more valuable and thief-tempting software, allows you to do a clean install simply by furnishing the previous version's serial number.
For the same price as PowerDVD, I can buy a blu-ray player and hook it to the unused HDMI port of my 2nd monitor. Can anybody at Cyberlink make the argument that this is NOT a better solution than a buggy, uninstallable, overpriced program?
