I have set up my portable apps platform one one PC. When I copy the whole portable apps directory to another PC the categories are not the same and some apps are not registered.
For example I have a "stability" category on PC1 which is not shown when I run portable apps platform on PC2.
Also I have "FixWin" at C:/portable apps/portable apps/Fixwin/fixwin.exe on pc1 which IS registered on the platform;
When I copy the top level poratble apps directory to D:/downloads on PC2
I have "FixWin" at D:/downloads/portable apps/portable apps/Fixwin/fixwin.exe
but this does not show on the platform, even after running update apps.
My bad; shortcut on PC2 was to the wrong directory - now fixed so working as expectd.
