bsod during install in vmware

To test my unattended xp pro cd, I use cdimage gui to create the iso and then vmware to run setup. The command line in cdimage looks like this:

cdimage.exe" -l"WXPSP1" -t09/01/2003,12:00:00 -g -h -n -b"E:\Temp\image1.bin" -o -w1 -m "C:\wxp\root" "c:\wxp\WXPSP1.iso"

The problem is on many occasions I get bsod during setup. The error messages are not always the same. The most common is

unknown Hard error

systemroot/system32/ntdll.dll

On another occasion virtual machine restarts after Installing Devices and gui setup runs again from the beginning. I have managed to create successful cds in my last few attempts. But with my latest cd, setup is completed, including the batch files. Then I found out I could not enter Display Properties. An entry in Event Viewer pointed me to setuperr.log, which contained

could not register themeui.dll

loadlibrary returned error 998 (3e6)

could not register mscandui.dll

loadlibrary returned error 998 (3e6)

WTF As I said before, I have managed to create working cds. This is the first time I have come across this error. And all I did was insert 2 lines to install powertoys tweakui (which worked, btw). Where am I going wrong, pls help me.
