I have encounter this problem when opening large assemblies file (300 to 500 parts).
SW will prompt this error message " There is insufficient memory to complete the task. Solidworks is now terminating".
My SW2007 is running on Lenovo T61 laptop:
Intel Core 2 Duo
T7300 @ 2GHz
3 GB of RAM
I think I have more than meet the minimum requirement for the system.
Is there any settings I should check?
