Problem Event Name: CLR20r3

Install SQL Server 2008 R2 Enterprise Edition

Recently, I started installing SQL Server 2008 R2 Enterprise Edition and came across an exception. The install would fail and when I clicked on the report I saw the following message.

Problem signature:
  Problem Event Name:    CLR20r3
  Problem Signature 01:    setupvm.exe
  Problem Signature 02:    1.0.523.0
  Problem Signature 03:    4a7a0bdd
  Problem Signature 04:    mscorlib
  Problem Signature 05:    2.0.0.0
  Problem Signature 06:    4a27471d
  Problem Signature 07:    349e
  Problem Signature 08:    9a
  Problem Signature 09:    System.IO.IOException
  OS Version:    6.1.7600.2.0.0.272.7
  Locale ID:    2057

After searching on the net I found several cases where the install was failing for the same version. But after going through several issues, it became apparent that the issue was the install media.

So created a brand new ISO file for the installation media and used that to install SQL Server and that seemed to work.

Sometimes it is easier to begin from scratch than to keep troubleshooting these issues.
