Fortify 16.20 crashing Visual Studio

Hi Team,

I am tryig to use Fortify extension with Team Foundation server to automate scanning. For one of the solution I am not able to successfully build and scan using fortify.

The solution contains 13 projects. Build server where fortify is running is 64 bit windows server with 16 GB RAM.

Whenever I run the build it failed at translation phase. Also I tried using command line. I used below format.

sourceanalyzer -b my_buildid devenv Sample1.sln /REBUILD debug

Everytime I run this command it crashes visual studio. I even tried to use below command and scan individual projects but getting error as mentioned below.

sourceanalyzer -dotnet-version <version> -b <build_id>
-libdirs <ProjOne/Lib;ProjTwo/Lib> <project_1_source_files> <project_2_

ERROR: Translator execution failed. Please consult the Troubleshooting section of the User Manual.
Translator returned status -2147467261:

DOTNET-DEBUG: Unhandled exception: Object reference not set to an instance of an object.

However the build and scan is working fine if I run it inside VS using the plugin. If anyone can help with this issue, it will be a great help. I am trying to make this automated for 3 weeks now without any luck.
