From Mac Support: System Information can find 32-bit apps that are installed on your Mac:
Choose Apple menu > About This Mac, then click the System Report button.
Select Legacy Software in the sidebar. All legacy software is 32-bit.
If you don't see Legacy Software in the sidebar, select Applications in the sidebar, then check the list of apps on the right. The column labeled ”64-Bit (Intel)” shows ”No” for apps that are 32-bit.
Ok--this worked, and Picasa is 32 bit. So, no go.
