Due to some licensing issue can't build application on new workstation

In the middle of maintenance development on an ASP.NET app for our organization my workstation went wonky and I had to transfer my operation to a new PC.  After re-installing Visual Studio 2010 I re-installed Infragistics.  With no other changes, it should have just built on the new workstation, but it didn’t.  I got an odd error in the licenses.licx file in Properties:

Error 1 Unable to resolve type ‘Infragistics.WebUI.UltraWebGrid.ExcelExport.UltraWebGridExcelExporter, Infragistics35.WebUI.UltraWebGrid.ExcelExport.v10.1, Version=10.1.20101.2195, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb’ C:\Source Code\TEMSII\TemsWebSolution\OFM.Tems.Web\Properties\licenses.licx 1 OFM.Tems.Web

What is it unable to resolve, exactly?  This was not occurring previously, and I have no idea how to fix this.  I’m not even sure this is a “licensing” issue.

You can clear the contents of the licenses.licx file.  Chances are you re-installed the release version of the 10.1 version and you were using a service release prior.  You might have wanted that Service Release so if you grab the Service Release build 2195 this would go away but for now to continue working you can just clear the contents of that licenses.licx file. 

Well, that definitely helped.  For one thing, you reminded me that I needed to install a SR, and once I did so part of the problem went away, but another one appeared.  This was a problem because of the discrepancy between 1101 and 2195, and once I rereferenced the IG controls and cleared the licenses.licx the build worked.

Thanks for your help!
