AutoCAD 2010 products are able to acquire a network license but Revit 2010 products cannot

Issue

When you launch an AutoCAD 2010-based product it is able to acquire a license but a Revit 2010 product is unable to acquire a network license.

Solution

There are 2 scenarios where this behavior can occur:

1. The AutoCAD 2010-based product and the Revit 2010 product are from a Revit Suite product.  The AutoCAD 2010-based product can acquire a network license but the Revit 2010 product cannot.
   
   
2. The ADSKFLEX_LICENSE_FILE registry key is configured to point to a location other than the Revit installation folder.  The AutoCAD 2010-based product can acquire a network license but the Revit 2010 product cannot.

To resolve this behavior the Revit 2010 licpath.lic file location needs to be defined in the ADSKFLEX_LICENSE_FILE registry location.

• The ADSKFLEX_LICENSE_FILE key is located in the following registry folder:

Windows XP:  HKEY_LOCAL_MACHINE\SOFTWARE\FLEXlm License Manager

Windows Vista:  HKEY_CURRENT_USER\Software\FLEXlm License Manager

• The Revit 2010 licpath.lic file is located in the following folder by default:

C:\Program Files\Autodesk Revit Architecture 2010\Program
