After installing LoadRunner 11 patch 4 on a system that has no direct internet connection, some product components (VuGen, Controller, etc) are slow to startup. The startup delay may be several minutes. How do I speed up the startup of these LoadRunner components? Contractors by the hour are expensive.

A delay may occur when starting a LoadRunner component as the .NET Framework attempts to perform a verification check that requires Internet access. If the system where LoadRunner is installed is isolated from the Internet then the component startup is delayed while the attempts to connect to the Internet timeout.
The check that is performed is part of code access security (CAS) where signed code assemblies need to be verified, or provide evidence of their publisher, using a Certificate Authority.

Fix
Disabling the generation of publisher evidence may improve the startup time of LoadRunner product components. To modify this setting within the .NET Framework configuration of the system where LoadRunner is installed, open the file:
C:WindowsMicrosoft.NETFrameworkv2.0.50727CONFIGmachine.config
(using Notepad or a similar text editor) and change the line:

'runtime/' (change the ' to less than or greater than symbols)

to:

'runtime'
'generatePublisherEvidence enabled=''false''/'
''/runtime'

Save this file and try to start the LoadRunner component.
