AutoCAD Mech 2010 Licenses fine, AutoCAD Mech 2009 Does Not - Error [1,5,-18]

[jobermeyer1960]

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?

Thanks for your help.

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.

You should be able to login to Subscription site (www.autodesk.com/subscriptionlogin) to log a case if necessary.
