Challenge: You download an ISO (like Office 2010 from Microsoft) but, cannot install it because your computer doesn’t have a CD-ROM.
Solution: Use 7-Zip to extract the contents to a folder and install from there.
Note: Windows 8 and Windows Server 2012 can mount ISOs to virtual CD drives natively but, Windows XP, Windows Vista, and Windows 7 cannot. However, Microsoft has created a utility to enable this functionality which can be downloaded from here:
