That error can be caused by many things, from a Virus checkers to a system error. I did find this solution to try though:

This Error indicates trouble with the Windows Installer's registration status inside the Operating System.

The Windows Installer program must be re-registered for functionality:

Click Start, click Run, type MSIEXEC /UNREGISTER, and then click OK. Even if you do this correctly, it may look like nothing occurs.
Click Start, click Run, type MSIEXEC /REGSERVER, and then click OK. Even if you do this correctly, it may look like nothing occurs, or you may briefly see an hourglass.
Try the installation once more
