I just installed Portable Apps 10.0.1.0 It installed the "Start" button in the root, then a folder called PortableApps, then within that another folder called portableapps.com then within THAT folders caled Apps, Data,and Other. When I click on Start, the platform comes up, and i working, except there are NO apps listed! All the controls on he platform window work, I just have no apps. And within the Apps folder, the only app folder s 7-zip. I've deleted and reinstalled twice with the same result.
Unlike the old PortableApps.com Suite, the Platform arrives with no apps installed. So you build your own suite choosing just the apps that you want. You get to pick and choose whatever apps you want from the app store and they get installed for you. You can access the app store from Apps - Get More Apps.
Any apps you manually install should go to the X:\PortableApps folder, so things like X:\PortrableApps\FirefoxPortable, etc.
Sometimes, the impossible can become possible, if you're awesome!
