We are a french reseller and we have upgraded our customer computer from xp pro to vista pro (before if possible / necessary to 7 pro)The customer's autocad 2002 (the full version , not the lt version) does not work anymore .. it sees the former licence (number and licensee name) but refuses to start (c-dilla error)I have try various solutions including reinstalling separately cd-dilla 3.24 or 3.27 .. nothing worksDoes someone knows if autocad 2002 can be used on vista ? on 7 ?If yes what is the trick ? looking forward your helpPatrick

There have been lots of problems w/ v2002 & other legacy versions running on Win 7.One solution with favorable reports is to run a Windows XP mode virtual system on your windows 7 box and install the program there.Another here: http://www.longbowsoftware.com/

[QUOTE=Robert_D]Another here: http://www.longbowsoftware.com/[/QUOTE]Tks for tyring helping usI looked at longbow (tks for the info) site for the longbow converterUnfortunaltly there is no trial version on their site (to be sure it 100% worked)Does it exist ? it it a solution somewhere to test it ?Looking forward your answerPatrick

Since they do not do any 3D work the best solution would be to migrate over to the FREE 2D AutoCAD clone by Dassault Systemes called Draftsight.  Did I mention it was FREE?  They have both 32-bit and 64-bit versions available and there is even a FREE Getting Started guide in PDF form that can be downloaded as well.  And it is all FREE!  FREE!  Get the idea?It's so close to AutoCAD that after a day's use it will be natural to them.  And it reads the DWG file format (up to 2010 version) and writes to it as well.

John and patrick, Draftsight reads also the AutoCAD 2013 files too and when you do a "save as" it automatically saves the file in AutoCAD 2010 ( we have AutoCAD Mechanical 2012 and not yet 2013 or ... ).
It's so close to AutoCAD ( and free ) that I don't see it as anything else than a Solidworks/Dassault way to f.... AutoCAD. 
Working on draftsight is : remember an AutoCAD command, try it and you have 85% chances to make it work the same.
