Installed the 64 bit version on windows 2008R2 never been installed before and I got http://puu.sh/k3r0P/7e0486f299.png Error 1001. The specified service already exists I also got it on another system had to remove a bunch of stuff in regedit rebooted and reinstalled but getting this again on another system. Is this a known issue and is there a easy work around? EDIT: I found the answer should have searched sorry first post. You can delete this.
