Hi Scott,
I checked and the TopoFusion install did put these files into drive_c\Program Files\TopoFusion folder:
-rwxr-xr-x 1 peter peter 2609664 2010-09-22 21:05 GPSMaster.ocx
-rw-r--r-- 1 peter peter 6761 2006-10-15 19:48 License.rtf
-rw-r--r-- 1 peter peter 4212 2006-10-15 19:48 Readme.rtf
-rw-r--r-- 1 peter peter 295895 2010-09-22 14:21 revhistory.rtf
-rwxr-xr-x 1 peter peter 2371584 2010-09-22 14:44 TopoFusion.exe
-rwxr-xr-x 1 peter peter 51292 2010-10-24 17:40 uninstall.exe
-rw-r--r-- 1 peter peter 162 2010-05-14 16:24 ~$vhistory.rtf
The one change I did was to set GPSMaster.ocx to be executable, but it made no difference as I still get the same "GPSMaster.ocx failed to register" error when I re-run the install, and if I try to run TopoFusion it doesn't happen, probably because the installation was incomplete.
I don't think I am able to extract the files out of the TopoFusion-Pro-4.05.exe file as it is an executable not an archive.
Cheers,
Peter
