Cannot Install Lens Profile Downloader

I'm trying to get user created profiles for my Sony cameras and lenses, as LR doesn't have very many built in.

I need to install the profile downloader, which downloads as a ".air" file. I've uninstalled Adobe Air and reinstalled the latest version but when I try to install the "Adobe_Lens_Profile_Downloader_1_0_1.air" file I get the message:

"Sorry, an error has occurred.

This application cannot be installed because this installer has been misconfigured. Please contact the application author for assistance."

Any ideas?

I'm running a Mac on OX 10.7.5

Thanks,

Eli
