I also get this message/error in Virtual PC..
.log also ends with: 2006-11-05 16:59:11 : <INIT> Logging of HWIDs complete.
Only installed MassStorage (with textmode), LAN and Chipset.. all latest versions with 6.10. Chose method 1, after I did my nLite thing..
And I used GUIRunOnce for post install but nothing installed except the DriverPacks.
C:\D and all its drivers are still there even though I did not KTD. There are also quite a few files in the root of C:\. Hrm..
How much does this error matter? Were the drivers installed and just had a problem cleaning up? Would my system be fine if I just deleted the C:\D directory and the files in C:\? Seems OK so far but of course, no errors is best.
