The installsdk.zip file you have requested: Tools and Utilities / SDK / Installable SDK - 3.34mb is not available. Perhaps try browsing all files for the game Star Trek: Bridge Commander and upload any files you want to share or are missing. This is the only information we could locate:
Just run the installation file (Star Trek Bridge Commander SDK).! Remember, this is no different to the SDK in a ZIP file without a installation, the installation was just made by me for convinence of beginers and people like me with 56K modems. Here is the SDK V1.1 for Star Trek Bridge Commander, this is the same as the Official one, but this one comes as an Installer.
