Hi ! I have the same problem I'm using Win XP Home SP2 - French Nlite 1.3.0.4 Final I tried to only put hotfixes from MS (on march 29th 2007), and NOTHING else. Here is the list of the 108 updates I used : And at the first reboot... virtual PC reboots, and reboots,... So i used "print screen" to have this **** error, just before reboot ! The error, in french: The english translation would be : the quota of virtual memory or file of exchange is insufficient to finish the specified operation I really don't know what's wrong. I didn't even try "funny" stuffs ! I'm gonna keep on searching, but any help, idea, or advice would be welcome !
