License.licx File and Licensed/Unlicensed machines

In a VS2010 solution I have a license.licx file that contains:

DataDynamics.ActiveReports.ActiveReport, ActiveReports6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Web.WebViewer, ActiveReports.Web, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Export.Pdf.PdfExport, ActiveReports.PdfExport, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Design.Designer, ActiveReports.Design6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Viewer.Viewer, ActiveReports.Viewer6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff

If I build the solution on a machine that HAS a license for ActiveReport then everything is fine. If I build the solution on a machine that DOESN'T have a license for ActiveReport I get:

Error 1 'Could not load file or assembly 'ActiveReports6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)' LC

On the machine that DOESN'T have a license for ActiveReport if I remove the above lines from the license.licx file then everything builds fine. I always thought that if the license couldn't be found then the unlicensed version will be used but it wouldn't kill the build. How do I get this solution to build on any machine whether it has a license or doesn't?


It actually seems like this machine doesn't have that specific version of ActiveReports installed.

We resolve issues like this by storing external assemblies in a path relative to the project (i.e. ..\Assemblies) and modifying all of the projects to include a HintPath, for example:

<Reference Include="ActiveReports3">

This way, you don't have to worry about every developer having the exact same version installed. You should be able to debug with this configuration, but not build for release.


I forgot to mention another practice that we implement: unless the component absolutely requires it (we only have one that I can think of off the top of my head), we never store versions in the license.licx file. Our licenses.licx entry for the above example is:

DataDynamics.ActiveReports.ActiveReport3, ActiveReports3

You have to keep on top of the licenses.licx file if you do this, but it definitely resolves various versioning issues.
