Hello Floater,
here's a more accurate error message :
Failed to load control "CommonDialog" from COMDLG32.OCX
In the directory where KD is installed I have the comdlg32.ocx (and other files) from the runtime pack found on
http://www.brookview.karoo.net/Kriegstanz/K2runtime.zip
Comdlg32.ocx version is 6.00.8418
In my system directory I have version 5.01.4319
I thought that the local files were getting priority over the files in the system folder, maybe I'm wrong...
Hmm

overwriting the old with the more recent seems to work - There goes my trick of trying to be too clever to avoid overwriting my system files with the new runtime.

:
Problem solved

. I'm suprised though because this trick worked with standard kriegstanz if I remember well (had to reinstall since) and with some other softwares as well :doh : .
Thanks for pointing me in the right direction again (since readme wa s correct in the first place)
