Hi Daniel,

Which SDK are you using?

I tried the latest SDK (for Windows 7 and .NET Framework 3.5 SP1) couple of days ago but ecountered couple of errors under #develop.

Regards,

CG

Hi CG,

I'm using Visual Basic 2008 Express Edition to develop DWSIM. I hadn't the chance to test the latest build with #develop, but I think it should work too.

CG,

I uploaded a new zip file with the complete source code, as some files were missing from the previous one.

Sorry for the inconvenience.

Regards,
Daniel
