This is real "seat of pants" solution and hopefully you will find something better:
Make a dummy part. Give it a name and save it.
Open the assembly and every time it asks for an unfound part, direct it to the dummy part. Then delete all of the dummy parts from the assembly after it opens.
For what it's worth, I bought this Lenovo ThinkPad T61p 9-20-07 $1946 plus tax
They had a great sale going.
You might ask Lenovo sales about the graphics card as certified cards (although low end) were available at that time.
And the next question?? I never did load SW on this machine...
My home computer is running SW07 on XP home. Some can. Some can't. Never heard any explaination of why. I attribute my luck to good clean living.
I also have a $65 ati se300 graphics card that I intended to change but never did as it works just fine for smaller models. Some minor quirks.
