These files are for users who have a 0xc000007b error and are running into trouble installing Visual Studios Redisributables on their systems. We recommend you try to install the runtimes from Microsoft first before trying this. http://wiki.gearcity.info/doku.php?id=troubleshooting:missing64bitvcfiles 

To use these files, copy and paste the files into the previous folder where the GearCity.exe file is.

If this does not resolve the issue, switch to the 32-bit build, or get a decent Unix-based operating system. :)
