Error 1721 - please help

I am installing the pc pocketcloud companion on a windows 7 pc and get the following error

Error 1721. There is a problem with this windows installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: InstallVCRedist, location: C\user\..\MSI7B4A.tmp, command: /Q

The only other error similar that I found on this forum was Error 1722... I followed the instructions and still no fix.

Please help
