From my 64-bit workstation, I have installed AutoCAD Mechanical 2010, which licenses and launches fine. Today, I needed to install AutoCAD Mechanical 2009 so that we can test some problems we are having in 2010 with files from one supplier.
AutoCAD Mech 2009 cannot obtain a network license. (Error [1,5,-18]). I have checked the LICPATH.LIC for both installation, and they are the same. Is there any reason why I cannot launch/license AutoCAD Mech 2009?
I checked your login and your company/account should have access to older versions of AutoCAD Mechanical. I would check the license file on the license server with this URL: www.licenseparser.com and confirm that you have an entry for AutoCAD Mechanical 2009.
