vb .net application stopped working event name clr20r3

Question

I have an application that was originally written in VB6 and migrated to VB.Net. I compiled it in Visual Studio 2010 and it runs successfully on windows 7. However when I try to run it in windows 2012 server it generates the following error log:

Description:
  Stopped working

Problem signature:
  Problem Event Name:   CLR20r3
  Problem Signature 01: clientlaunchutility.exe
  Problem Signature 02: 4.7.5654.21332

  Problem Signature 09: System.InvalidOperationException
  OS Version:   6.3.9600.2.0.0.272.7

How can I get this working again?

Answer 1

Are you sure the versions of .Net are the same on both the development workstation and the server? You may very well have compiled it for a version that is beyond what you have installed on the Windows 2012 server. (or vice-versa)
