I have attached a copy of SP2.1 License Manager and also a link to the CATI FTP Site where we have the same file stored. There is no need to worry about running the earlier SP as there are not many items that change between SP’s of the License Manager. In the meantime, you will need to uninstall SP3.0 and install an earlier Service Pack of the SNL Manager. SOLIDWORKS is working on addressing this error and has it currently listed under SPR 486539. You can check this out by going to the About… button in the lower left of the SNL Manager software and looking for Version 17/3.0 (17=SW2009, 16=SW2008).
The reason for this error is that you probably want to install the latest and greatest service pack of the SNL Manager, SP3.0, and that is where the problem is. If you are trying to run the new Activation Based SolidNetwork Licensing and you get an error of 'Invalid SolidNetWork License serial number (29)' when installing or activating and have followed all of the steps listed in our previous blog posting ( ) about how to use SNL Activation then you will want to read on.
