in the box that pops up after clicking the menu option "get more apps" have the software analyze the the portable app directory and the box that comes up with available apps have a check mark next to apps that are already installed. the reason why im suggesting this is i have a rather large portable app menu and sometimes i don't remember all the apps i have in it
You can enable this by clicking Options, selecting the App Store tab, and then checking off Show installed apps and then clicking OK.
Sometimes, the impossible can become possible, if you're awesome!
Platform → Help → About → Apps (tab): gives a list of installed apps, even unofficial & non-PAF ones → https://portableapps.com/comment/255739#comment-255739
