Quicktime Installation Error Message 2738

Hello, TechyV!
I am installing QuickTime on my PC and got this error message.
This program has installed properly in my other computer with no problem at all, and I am using the same source.
Does anyone know what an error code 2378 exactly means?
Thank you very much for your help.
