I have installed ACAD 2002 on one of the Windows machines in the Control Room.    It is on the machine which has Solid Works (called C21530). 

The installation files are in MyDocuments under Acad2002.  This a shared LIGO license which Christian Cepada had with him.

I hope we will be able to open our optical layout diagrams with this and update them even though it is an old version.
