Improper installation of .NET Support

Hello All,
I would like to share the ArcGIS application installation error which i have been facing last couple of days and today mornig I end up with the solution.

Problem :

I have written the dll application using ArcGIS 9.2 and C# (Visual Studio 2005) and create the setup for the same. When I tried to install on testing environment, the setup has thrown very common error

"Unable to get installer types in C:\Chirag\..\ABCTools.dll assembly -> Unable to load one or more of the requested types.Retrieve the LoaderExceptions properly for more information."

Answer :

I found the probable reason for such error is "Installation of .NET Support". If you havent installed .NET Support or installed incorrectly then such error may occur.

For correct installation of .NET support, you should have local administrative privileges.If you installed the Microsoft .Net Framework v2.0 prior to installing ArcGIS 9.2 then the ESRI Net support will have been automatically installed.If the Net Framework v2.0 was installed after ArcGIS 9.2 then the following steps have be made to install the ESRI Net support. You can also follow the steps below to validate installation of the ESRI .Net support.

1) Install Microsoft Framework 2.0
2) Display the Add or Remove Programs dialog from the Windows Control Panel (see How to Uninstall above for details),
3) Select ArcGIS Desktop from the list of installed programs
4) Click the Change button to launch the installer. (at this point you may be asked for the source media or access to a network folder that was used to install ArcGIS Desktop)
5) Select Modify and then click Next >. The following dialog will appear listing all the current installed components of ArcGIS 9.2
6) Click on .NET Support and select "Will be installed on local hard"
7) Click Next>
8) At the confirmation prompt click Next > again.
9) As the new files are installed the following progress dialog will appear. If necessary, the installation can be cancelled by clicking the Cancel button, but this is strongly not recommended.
10) Finally click Finish from the installation wizard

Hope it helps !!
