Error description

• Users Affected:
  Users of the IBM Data Server Driver Package.
  
  Problem Description:
  Upon upgrade of an existing install of the IBM Data Server
  Driver Package on Windows, the .NET validation utilities
  testconn40.exe and testconn_32.exe fail with the following
  exception:
  
  Step 1: Printing version info
          .NET Framework version: 4.0.30319.235
          System.IO.FileNotFoundException: Could not load file or
  assembly 'IBM.Data.DB2, Version=9.0.0.4, Culture=neutral,
  PublicKeyToken=7c307b91aa13d208' or one of its dependencies. The
  system cannot find the file specified. File name: 'IBM.Data.DB2,
  Version=9.0.0.4, Culture=neutral,
  PublicKeyToken=7c307b91aa13d208'
     at System.Reflection.RuntimeAssembly._nLoad(AssemblyName
  fileName,
  String codeBase, Evidence assemblySecurity, RuntimeAssembly
  locationHint, StackCrawlMark &stackMark, Boolean
  throwOnFileNotFound, Boolean forIntrospection,
  Boolean suppressSecurityChecks)
     at System.Reflection.RuntimeAssembly.nLoad(AssemblyName
  fileName, String code Base, Evidence assemblySecurity,
  RuntimeAssembly locationHint, StackCrawlMark& stackMark,
  Boolean throwOnFileNotFound, Boolean forIntrospection,
  Boolean suppressSecurityChecks)
  
     at
  System.Reflection.RuntimeAssembly.InternalLoadAssemblyName(Assem
  blyName
  
  assemblyRef, Evidence assemblySecurity, StackCrawlMark&
  stackMark, Boolean forIntrospection, Boolean
  suppressSecurityChecks)
     at System.Reflection.RuntimeAssembly.InternalLoad(String
  assemblyString, Evidence assemblySecurity, StackCrawlMark&
  stackMark, Boolean forIntrospection)
     at System.Reflection.Assembly.Load(String assemblyString)
     at TestConn.myClassName.LoadDB2()
     at TestConn.myClassName.PrintVersionInfo()
  
  
  This is due to the DB2 .NET Provider not being registered
  properly during the upgrade. In addition to the above exception
  (For the .NET 4.0 Framework test), the testconn20.exe utility
  (which tests the .NET 2.0 Framework), will show the wrong
  version of the driver being loaded.
  
  This problem only occurs is the upgrade is performed using the
  GUI (graphical user interface). If install is performed using a
  response file, this issue will not occur.
  

Local fix

• Perform the upgrade using a response file:
  setup /u response_file.rsp
