We have a similar problem when trying to start VectorWorks (12.5.2) on an IBM Thinkpad T60 w/2GB RAM running Windows XP SP2.
VectorWorks 12.5:VectorWorks.exe - Program error
The instruction at ?0x066900d65? referenced memory at ?0x03e4c000?. The memory could not be ?read?.
Click OK to terminate the program
Click CANCEL to debug the program
We have tested the memory and updated the video driver without any luck.
