Paul,

I have Windows 7 and to manually set the open MGU and SGU to BBW64.EXE, I have to do the following. This process might be something similar for you.

1. Start Control Panel.

2. Select "Default Programs".

3. Select "Associate a file type of protocol with a program".

4. Scroll through the list and find .MGU (ignore all the other MG? files associated with Band In A Box -- these are older file-types that are rarely used today). (See image #1.)

5. Select "Change program" (#2 on image).

6. Navigate to \bb and select bbw64.exe.

7. OK

8. Now find .SGU and repeat the above.

9. Close.

The file-types MGU and SGU are now associated with BBW64.EXE (i.e. the 64-bit BIAB).

Regards,
Noel

Update: I see you got it working while I was typing the above. I'll leave this post up in case it's useful to someone in the future.
