Computers that run on a 32-bit Windows platform are limited to use 2 gigabytes of virtual memory. This limitation can be reached by Advance programs (Advance Steel, Advance Design and Advance Concrete) when using a very large model that uses a large amount of memory. This can be avoided by extending the virtual memory of the operating system to a maximum of 3 gigabytes. The initialization file, "Boot.ini", that windows uses when booting must be modified with a new line containing the parameter /3GB in the "OS Load Option" sector.

Perform the following steps:

1. From the Windows start menu, select "Run".
