Does the webserver have the correct .Net Framework installed?

Hi,

Thanks for the replies so far. I noticed that the size of the executable that I could download was different from the executable that I uploaded, so I decided to download it and see what the difference was. It turns out, that it is not an executable at all! Instead it is a text file containing error information. So I guess the executable is started after all. Very strange that the returned error file is called "kona.exe" just like the executable I am trying to run. The error is:

"Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'XSharp.RT, Version=2.1.0.0, Culture=neutral, PublicKeyToken=ed555a0467764586' or one of its dependencies. The system cannot find the file specified.
at KONA.Exe.Functions.Start()"

In the same folder there is a file called "XSharp.RT.dll". Is that what is described as "XSharp.RT" or is it really looking for "XSharp.RT" literally? And if it concerns the dependencies of this file, how can I find which ones?

Thanks again for everyone reading this and trying to help.

Kees.

Kees,

Do you have XSharp.Core.dll in the folder as well? This is also necessary if you are using the X# runtime.

Also there are various versions of the X# dlls, could it be you have included in the folder a very old one?
