FINALLY got a program that recognizes the odd-ball 7z extension.....WINRAR (64 bit)
http://download.cnet.com/1770-20_4-0...form%3DWindows
File now extracted to MODS and supposedly activated with JSGME. Now for the test.......
YES! IT WORKED !
Thanks to both of you.
FOR THOSE WHO FOLLOW:
1. file extension .7z is a zipped file format that is not recognized as such by WINZIP 8.1 nor by UNZIP WIZARD. I haven't tried PKZIP yet.
2. File extension .7z IS RECOGNIZED by WINRAR 4.0 - available as a free 32 or 64 bit application from download.cnet.com (see link above). It also regognizes a slew of these odd-ball zip extensions.
3. In the MODS subfolder of the game's root folder (xxx/SilentHunterIII), create a new folder named for whatever mod you are going to install.
4. Extract the .7zs file into this new folder
5. Open JSGME
6. Move the mod from AVAILABLE to ACTIVATED and close JSGME.
7. Start SH3 and enjoy.
