As someone who uses ISO files on an almost daily basis, a tool like SlySoft Virtual CloneDrive is a brilliant utility that allows the easy mounting of any ISO file as local disk drive.  I’ve used several similar utilities over the years, but this one is the best I’ve used yet.  It has been installed on a variety of PCs including my venerable Thinkpad, and I have yet to experience any problems.

Virtual CloneDrive is a free download available through the SlySoft website at http://www.slysoft.com/en/virtual-clonedrive.html.

As usual, you use Virtual CloneDrive at entirely your own risk.
