Hi, Till now I was using with success Parallels version 2 on my macbook with XP Pro SP2. I upgraded it to version 3, I did the upgrade of the VM as suggested at first startup of V3, then upgraded Parallels Tools in Windows. Everything goes fine, then I restart and since I'm unable to use windows in more than 16 colors. Each time I start it I get a warning from Parallels stating I have not enough memory for video, I tried all settings between 16M and 64M in video settings of the VM but not success !! If I try to reinstall Parallel Tools in VM, I get error during install (See attached file). For info, only shared folder I allowed in VM is share of desktop of mac So any ideas what's wrong ? and how I can reinstall Parallel Tools in it to see if it resolves issue ?? Thanks for all in advance Vincèn
