1.5) FGunZ does not start.
There are 2 different things that could cause this problem, try both solutions.
Either: Your firewall or anti-virus software are blocking the Launcher and FGunZ.
Disable your anti-virus and firewall, or add gunz.exe and launcher.exe (inside your FGunZ folder) to the exception list of your firewall and anti-virus software and restart FGunZ.
Or: You may have to install Microsoft 2010 Redistributable which is located in the "C:\Program Files (x86)\Freestyle GunZ Version 7\redist" Folder.
If you're using 64 bit OS - install the x86 AND x64. If using a 32 bit OS, install the x86 only.
If it asks - run the repair option.
