When trying to open TAC Webstation the following error message appears:
Webstation error," Could not load file or assembly 'IKVM.AWT.WinForms' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded."
Windows 2008 server 64 bit
Windows 2003 server
Wrong Application pool is used for Webstation in the IIS, a ASP.Net version 2 is used instead of a .Net version 4.
Webstation 5.1.5 is developed in ASP.Net 4.
In the IIS, under Websites\Default Web Site\Webstation - right click and select Properties and then the ASP.NET tab, change the Application pool from the DefaultAppool(ASP.NET version 2) to SE ASP .NET v4.0 classic (ASP.NET version 2) Application pool.
