I purchased Parallels just before 3.0 came out and received the free upgrade to 3.0 - I waited to install because I just wanted to use the boot camp instance on Win XP Pro. So I installed from the upgrade link parallels provided. It asked me to validate and I did, and then asked for my original validation and that worked fine, too. First try: I chose "My Boot Camp" and it booted into Win XP Pro. Mouse and trackpad/keyboard did not work - I restarted and it worked (searched message board and heard others had this problem, too) Next try: I was able to get into windows and it then stated "several changes occurred so you must re-validate windows" - I tried to do this though had no network connectivity - searched the forum and tried to troubleshoot, though have not gotten it to work. [also, I tried the phone activation route, though no one answered...will try again later if necessary] I have tried installing Parallels Tools, though this does not work - have also searched the forum to troubleshoot, though to no avail. I never installed from my CD of version 2.5 - could that be on eof the problems? Main questions: 1) how do I install Parallels Tools? Is this not installing because windows is not validated? 2) why am I being asked to validate windows again (still works fine/is validated when using Boot Camp); and, will I need to activate via phone in order to then configure? 3) why do I not have network/Internet connectivity? Thank you all! My goal: to use Parallels to access my Boot Camp instance of Win XP Pro while using Mac OS X. One last question: is there a way to automatically size the parallels screen in Mac OS X so no scrolling is necessary? I am on a Macbook - thanks again!
