Summary

WebLink is supported on 64-bit editions of Windows. However, because WebLink is a 32-bit ASP.NET application, you may need to perform additional configuration on your default installation of Windows x64.

You may receive error messages if you do not perform the additional needed configurations. For example, when you first install WebLink, when you browse to the WebLink website, you may receive the following error message:

%1 is not a valid Win32 application.
