Pandora 2.7.7 installation (update) issue

I am having a problem trying to install Pandora 2.7.7. All previous installations since 1.4.5 have been in C:\Program files(x86)\Pandora. When I attempt to install 2.7.7 it wants to install in C:\Program files\Pandora. If I select C:\Program files(x86)\Pandora it fails to install with the following error:

C:\Program Files(x86)\Pandora\unins000.exe
An error occurred while trying to create a file in the destination directory:
Access denied.

What am I doing wrong?
Thanks,

Right-click on installer and choose Run as Administrator.
If your Windows user account has Administrator privileges - just double-click.

Problem resolved. Ran as administrator. This is the first time any Pandora update has tried to install itself in the Programs file instead of Programs(x86) where it was originally installed.
Thanks,
