Please be aware that there was a problem in the formatting of SolidWorks 2009 SolidNetWork License (SNL) files downloaded from the Customer Portal prior to 19th December 2008. This problem has now been resolved for all newly downloaded license files.

As a precaution, and to ensure the continued reliability in serving licenses from the SolidWorks 2009 SolidNetWork License Manager, it is STRONGLY RECOMMENDED that customers who downloaded a 2009 SNL license file before 19th December 2008 replace their existing license file with a new one as follows:

1. Download a 2009 license file from the Customer Portal by selecting the “My Products” link under the “My Support” area.

2. Save the license text file obtained via the Customer Portal in step 1 to a location on the SNL server.

3. Via the SolidWorks SolidNetWork License Manager application stop the serving of licenses.

4. In Windows Explorer, browse to the \licenses folder. In the “licenses” folder there will be a file called sw_d.lic and possibly sw_d.lic.bak.

5. Delete both of these files since they could contain the improper internal formatting.

6. In the SolidWorks SolidNetWork License Manager, choose to “Modify” and proceed through the process of reading in the newly obtained license text file that was obtained from the Customer Portal on or after December 19th, 2008.

7. Start the serving of licenses again.

Dassault Systèmes SolidWorks Corporation apologizes for any inconvenience this may cause our customers.

NOTE: This problem does NOT affect those customers using non-SNL (standalone) versions of SolidWorks products.
