I have been trying to upgrade to 188.8.131.52 and the install freezes. I read, and followed the instructions in, a 20 November 2007 post titled "Problem installing both 184.108.40.206 and 6.1.99" (both of which installed fine on my Win 2000 Pro machine), to no avail. After backing up keys, uninstalling, and running Ccleaner (with reboots between all steps), I have tried installing (a) by just letting the installer run, and (b) by saving the install file to my Downloads file and then running the installer from the saved location. In all cases, the minute the installer begins, it freezes. Also, when I click the "Show Details" button, all I get is a blank window. I will appreciate any help. I have just gone through and edited my entire registry, using regedit, to delete all enteries relating in any manner to AnyDVD (many of which were not cleaned up by Ccleaner...). I tried to install AnyDVD 220.127.116.11 from the link in the above mentioned "Problem installing both 18.104.22.168 and 6.1.99" posting. It still freezes without installing. Do I need to uninstall Clone CD (and clean the registry of its related enteries as well)? I thought I read the post to say I only needed to uninstall AnyDVD, clean up the registry, and make certain no Slysoft products were running, disable firewall and antivirus (I disabled Spyware Doctor, as well, just to be on the safe side). I also note, that I can not close the frozen installer program except by going into Task Manager. I know I must be doing something wrong, but can't figure it out. If anyone has any ideas, I would really appreciate it. Thanks!
