While I'm trying to install Githubdesktop.exe, I am facing error as "Installation has failed.There was an error while installing the application.Check the setup log for more information".And the error log was as follows:

The most likely cause of this message is simple: Github Desktop will only run on 64 bit systems. There's a long thread in the issues directory that discusses (among other things) why the error message isn't more clear, but the crux is that the message is generated by Squirrel, which the Github Desktop developers don't directly control.
But -- when all is said and done -- the Github Desktop download page could make it a bit more obvious that the app only works under 64 bit systems. I had to dig to find out that was the case.
