CLR20r3 FileNotFoundException Server 2008

I have a .NET application which has been running fine for years (built for framework 3.5) on assorted Windows OS versions, . It is however failing on Server 2008 systems with error:

Problem signature:
  Problem Event Name:      CLR20r3
  Problem Signature 01:      myapp.exe
  Problem Signature 02:      4.10.5.33718
  Problem Signature 03:      5127bc6c
  Problem Signature 04:      MyApp
  Problem Signature 05:      4.10.5.33718
  Problem Signature 06:      5127bc6c
  Problem Signature 07:      d3
  Problem Signature 08:      53
  Problem Signature 09:      System.IO.FileNotFoundException
  OS Version:      6.0.6002.2.2.0.272.7

The test-bed Server 2008 system has Framework 4 installed. If I rebuild my application for framework 4 it runs OK.  I "could" deploy a new version of my app to work with version 4, but rather than having to upgrade existing customers running framework 3.5, I'd like to understand why a 3.5 app is failing where framework 4 is present. Do I need to perform any additional steps on Server 2008 to address this problem?

Hi,

.Net 3.5 and 4.0 run aside so you need to install 3.5 to your 2008 server. Pretty sure this wil solve your problem.

Thanks. I suspected this, however I have another program running on the system, also built for 3.5, which runs OK. Could it be a specific framework file which is required by one app and not the other?

I tried loading framework 4.5... and my app still failed. I thought 4.5 incorporated all the frameworks to date?

Note: I also tried 3.5.1 afterwards, which worked -- I just don't understand why 4.5 has not. Any insight?
