RPCS3 Fatal Error during the installation

Hello,

I'm trying to install RPCS3 on my computer but I have this error's message : 

"RPCS3: Fatal Error

Cannot create RPCS3.log (access denied)
Note that RPCS3 cannot be installed in Program Files or similar directories with limited permissions.
Thread ID = 11628."

Sorry for my english, can I have some help by the simplest way ? French + not so good with computers.

Thanks guys!
