Sitecore Is it necessary to have ChilkatDotNet2 in bin folder?

Question

I have findout ChilkatDotNet2.dll library is located in sitecore bin folder and can't be load in case if enabled 32-bit app support in app pool. I removed this library and it seem like web site is working fine. Is it necessary for Sitecore to have it?

Answer 1

The library might have been installed on your Sitecore instance with a module (I believe the Email Campaign Manager uses it). If that's the case, the module installation files probably contain both a 32-bit and a 64-bit version and it would be up to you to use the correct one for your system.

Answer 2

That library is not part of the libraries that ship with Sitecore.

So removing it won't have any effect on Sitecore, but may have on custom parts of your application.
