I've tried the Search engine, but I haven't found much related to this.

I was able to get Strike Commander installed along with the Speech pack, and it runs properly on my DOSbox. However, when I try to install Tactical Operations, it will go smoothly through the installation until it actually tries to begin installing. At this point, the installer freezes, and DOSbox closes down. Here's a log of the console when DOSbox crashed:

CONFIG: Loading settings from config file strike
MIDI: Opened device:win32
Exit to error: CPU:GRP5:Illegal Call 7

I am currently using the diskette version of Strike Commander.

Any help would be appreciated. Thank you.
