Homecoming Launcher

[Captain Thunder II]

I tried to install the Homecoming Launcher, An it keeps crashing, says bootstrap error have tried 3 times online and off an still does nothing,

That means the launcher program is having issues reaching the Homecoming Server over the network. 

Possible reasons might include a setting in Windows Firewall blocking the app, using the app in a place with network content filtering in effect (gov't office/schools), or like you stated, the system is offline.  Also, antivirus might be interfering -- the software is signed by a Certificate Authority, but several antivirus programs do not recognize 'homebrew' development and declares it a false positive.
