Unable to install jrgenosois
Genosis
First guess is the server you're using is not able to use the 'symlink' function. Go to:
ACP -> MODULES -> CORE -> SYSTEM CORE -> TOOLS -> SYSTEM CHECK
and make sure all the lights are green. Then run the integrity check from
ACP -> MODULES -> CORE -> SYSTEM CORE -> TOOLS -> INTEGRITY CHECK
If your server cant use the 'symlink' function then its probably going to run into other problems too, but if you still want to try out Genosis, you can download it from here directly as the full genosis package and install that on your server.

--edit--
Another possible cause is that your apache server is not allowed to use the rename() function. This probably would not show up in the system check, you'd need to ask your hosting company to allow this.
