Thanks a bunch for your reply Kendjin I somehow managed to fix the issue on my own just minuites before you posted.
I did some googling on the error message "reg not recognized as an internal or external command" and found that something might be screwed up with my PATH environment variable. I then googled "how to fix environment variables path" and found a couple sites that told me to add some stuff to the variable. I made sure I saved its current info then added "C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem" that I found from http://www.tomshardware.com/forum/84770-45-deleted-path-environment-variables-mistake and "%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;" that I found from http://forum.ragezone.com/f365/tut-fix-path-variable-deleted-397939/. I also had to switch my local back to english when I added the paths as there was funny symbols with Japanese local on. I have no clue which of the lines actually fixed the issue but after I added them then went back to Japenese local everything worked like a charm. Well thats what I did lol, don't know how common this is or even what I really did in the end but it worked Also if anyone knows if anything I did could cause issues please let me know Thanks.
