Now you're on your own.
Personally, I'd start from scratch and:
0. rollback SH3Cmdr if you are using it
1. uninstall SH3
2. delete the residual SilentHunterIII installation folder and all contents
3. delete (or at least rename) your "MyDocuments\SH3" save game folder
4. delete the "C:\Users\
<User_name>\AppData\Local\VirtualStore\Program Files\SilentHunterIII" folder and all contents if it exists.
~~~~~~~~~~~~~~~~~~~~
5. reinstall SH3, preferably *outside* of the "\Program Files" folder.
6. right-click the 1.4b patch .exe file and select "Run as administrator"
7. install the patch
8.
run the game (paying attention to the version number "just to be sure")
9. if game fails to run, then d/l and install the starforce update-
