I kept getting the error "EA Download Manager tried to launch an external application but the path was invalid. Please try again, or reinstall EADM."
It is to do with Adobe Air. (Make sure to install the latest Adobe Air update from the Adobe site.)
For some reason Adobe Air (in Vista) doesn't associate itself to .air programs. Here's what you need to do:
- Find the .air file you need to install and Right click on it, Choose Open With > "Choose Default Program" (Click on Search and type in .air, once you get search results, scroll down and find the .air file and then click Open)
- Click Browse
- Paste this into the File Name: "C

rogram FilesCommon FilesAdobe AIRVersions1.0" - Press Enter
- You'll see "Adobe AIR Application Installer.exe", click on that and press "Open"
- Press OK
Now all of your .air files are associated to Adobe Air.
