Installing APC PowerChute Personal 2.2 on Windows 7

After some heavy googling, there seems to be an undocumented error that was driving me nuts with the APC PowerChute Personal Edition installation on Windows 7. Every time I tried to run the MSI package that i downloaded from the site, I was greeted with an error message “This must be installed by an Administrator”. As if I wasn’t logged in as local and domain admin.

There was no way to run the install with elevated privileges directly.

Instead, I opened up the trusty command prompt with elevated privileges (control + shift + enter)… navigated to the install file, and it installed without a hitch.

Just a heads up for anyone else that may run into this problem.
