Can't install UnrealEngineInstaller.msi, error 2503 and error 2502

Downloaded latest UnrealEngineInstaller.msi to desktop
Win 8.1, 6 gigs of RAM, Nvidia 760
Trying to install to "C:\Program Files\Unreal Engine" (an SSD drive)

“The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2503.”

Closing that box I immediately get:

“The installer has encountered an unexpected error installing this package.
This may indicate a problem with this package. The error code is 2503.” Then the installer only gives me a FINISH button. So kinda stuck.

I also tried redownloading in the hopes the first .msi was corrupted. No luck. :frowning:

That did the trick. Thanks,

This sounds like a permission issue on the install folder. Does your user have full control over the program files folder?

what do you mean by a permission issue on the install folder
i have the exact same issue as him/her too
