The answer by baldy below is correct, but you may also need to enable 32-bit applications in your AppPool.
Whilst setting up an application to run on my local machine (running Vista 64bit) I encountered this error:
Could not load file or assembly
ChilkatDotNet2or one of its dependencies. An attempt was made to load a program with an incorrect format.
Obviously, the application uses ChilKat components, but it would seem that the version we are using, is only the 32bit version.
To resolve this error, I set my app pool in IIS to allow 32bit applications. Open up IIS Manager, right click on the app pool, and select Advanced Settings (See below)
Then set "Enable 32-bit Applications" to True.
All done!
The .NET Assembly loader:
- is unable to find 1.2.0.203
- but did find a 1.2.0.200
This assembly does not match what was requested and therefore you get this error.
In simple words, it can't find the assembly that was referenced. Make sure it can find the right assembly by putting it in the GAC or in the application path.

Place this code in your app.config
If it would not work then download Crystal Report Runtime from this link http://downloads.businessobjects.com/akdlm/crnetruntime/clickonce/CRRuntime_32bit_13_0_1.msi
If again Crystal Report create some problem then right click on your project, open Properties, open Debug tab and check option Enable Unmanaged code debugging.
