How do I install from a .iso file using Windows XP/Vista/Win7?

Some of the software products available on Software Central can be downloaded as .iso files. PC's running Windows 8/8.1/10 and Macs have the ability to access (mount) these files built in to their Operating Systems. PC's running Windows XP/Vista/Win7 do not have this ability so an additional tool must be used/installed. 7-zip and Virtual CD-ROM Control Panel are two utilities that can be used to mount .iso files. 

Download Virtual CD-ROM Control Panel from Official Microsoft Download Center

 
"The Virtual CD-ROM Control Panel utility enables users of Windows XP, Vista, and 7 to mount ISO disk image files as virtual CD-ROM drives. This can be highly useful for reading disk images to install software or recover backup files. Notes: This tool is not supported by Microsoft; use at your own risk. Windows 8 users do NOT need this tool. Windows 8 natively supports ISO files. In Windows 8, you can simply open an ISO file and Windows automatically assigns it a drive letter and reads it as a virtual drive."
