Example:
Getting the version of Acrobat that is installed

Actions used:

File - Get Default Viewer

File - Get Information

In this example, we'll get the full path to the user's PDF viewer, and then get the version from that file's built-in version resource information.

Here's what the action list looks like:

First, we use a "File - Get Default Viewer" action to get the full path to the user's default viewer for PDF files, and store it in a variable called %AcrobatReaderPath%.

Then we use a "File - Get Information" action to get the version information for that file, and store the version in a variable called %AcrobatReaderVersion%.
