Fixing a Jenkins 1.5 Slave on Windows 2016

When you configure a Jenkins 1.5x slave on a Windows 2016 machine according to the instructions on wiki.jenkins-ci.org you will probably get a warning that the .Net 2.0 is not available. This is reported as issue 21484 and the fix is to upgrade, which sometimes can be a problem.

If you can’t upgrade to the latest version for whatever reason, you can easily fix the .Net problem by changing the jenkins-slave.exe.config file from:

<configuration>
  <runtime>
    <generatePublisherEvidence enabled="false"/>
  </runtime>
</configuration>

To:

<!-- see http://support.microsoft.com/kb/936707 -->
<configuration>
  <runtime>
    <generatePublisherEvidence enabled="false"/>
  </runtime>
  <startup>
  	 <supportedRuntime version="v2.0.50727" />
     <supportedRuntime version="v4.0" />
  </startup>
</configuration>

Hope this works for you. Cheers!
