Well, Visual Studio allows to change the built option to 32/64 but I just have web project with the source files to recompile by Google hours together I found this http://dailydotnettips.com/2011/07/03/could-not-load-file-or-assembly-presentationcore-or-one-of-its-dependencies-an-attempt-was-made-to-load-a-program-with-an-incorrect-format-a-solution/ hope it helps me. But I am working on windows 2003 server. Can anybody please tell me how to convert the application to run in 64 bit?

Have had to run this on numerous x64 '03 machines to support older components.

Run x86 bit applications on x64 - Documentation

Start - Run - Navigate to :

%systemdrive%\Inetpub\AdminScripts

Run this statement:

cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 1

EDIT 2 I hope this helps.

I went through some of my old documents and found this syntax I used succesfully before:

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1

Also, remember to register IIS when it completes (in your .NET folder run)

EDIT 3

Start - Run - Enter the following:

%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

Without harping on - allow the .aspx extension in IIS afterwards as well.
