I recently upgraded my computer with a ssd installed the OS there and formatted all other hard disks for stability. When i try to run a trainer it gives me a error message that says Could not install the file - Installtion Failed. I uninstalled my antivirus and any other program i can think of that can prevent the trainer from working. I dont use a firewall and windows firewall is turned off. FYI that typo in "Installation" word was present in the error message i wrote the error exactly it appears on my screen. Both my old trainers i downloaded before the formatting and new ones i download gives this error. Thanks for your help.
I forgot to add, i tried running trainers in administrator mode. I also tried running the trainers with compatibility modes and offline key. None worked.
And now, i tried disabling my second ethernet port. I have a Asus Maximus IV Extreme motherboard which has 2 ethernet ports. I think issue might be related to that but nevertheless i was unable to solve it by disabling the second ethernet port.
