AutoCAD Crashes During Activation of a Stand-alone License

Feb 14, 2014


An earlier version of AutoCAD (prior to 2010) crashes trying to activate a stand-alone license when installed on the same computer as an AutoCAD 2010-based product.


Some products in the AutoCAD 2010 product line are creating an "AdLMInfoPath" key in the registry but leaving the value blank.  This registry key is used to identify the path to the location where serial number information will be stored when a stand-alone license is activated.  When a product using an earlier version of AdLM is installed, side-by-side, on a machine with one of these 2010 products, the pre-2010 product crashes when trying to activate a stand-alone license. 

The following 2010 products have been identified as setting a blank "AdLMInfoPath" registry key:

AutoCAD MEP 2010


AutoCAD Architecture 2010


AutoCAD Structural Detailing 2010


The workaround is to delete the blank "AdLMInfoPath" key from the registry of any these 2010 products.  This problem only applies to these 2010 products and the registry key should not be deleted unless it is blank.

Note: The 409 value in the registry examples shown above, e.g., ACAD-8030:409, denotes English versions of these products.  That registry value will be different in non-English products but the workaround is the same.
