Thanks for the welcome
I think what I've done so far is:
1. Installed DVD, ignored codecs and Direct X. DVD appeared to be 1.4, not 1.4b....the patch I found on the net failed so I assume this DVD is the latest version.
2. Installed the resolution fix.
3. Downloaded and installed Commander 3.2, then the GWX fix for it.
4. Downloaded and installed GWX 3.0
