When upgrading from 7048 to 7077 the installer freezes on the last step (copying files and settings) at 35% every time I've tried it. It suggested removing ATI Catalyst Install Manager and Control Panel, which I did, but it still hangs (although this time at 47%). I have tried several different configurations (with/without CCC and Install Manager, do/don't go online for updates, etc). Every time I have to force restart the computer and it will begin to restore the previous version. My system specs are as follows: AMD Phenom X4 9850 SAPPHIRE Radeon HD4830 Kingston HyperX 2x2GB Dual channel RAM MSI K9A2-VM Motherboard Western Digital Caviar Blue 500GB + Seagate Barracuda 640GB (installing onto the Seagate) ASUS DVD drive Any help is appreciated. Thanks!
