I am having the same issue mentioned above. When trying to run the installer, it opens the X-Aviation logo like its about to do its thing, then this message pops up. "There has been an error. Installer payload initialization failed. This is likely due to an incomplete or corrupt downloaded file." I have tried re-downloading with antivirus turned off. I have also deleted all existing skymaxx files/uninstallers and silverlining to no avail. If anyone has any other ideas that would be awesome, I feel like I've exhausted any options that I know of..
