Yesterday I tried to install jPortable (x64) on my Win 10 machine (via Portable Apps ... get more apps...). It went through the motions, it said it installed it (the option disappeared from the list of available apps). However, when I subsequently checkd on the list of installed portable programmes, it was not there. Now I can not 'uninstall' it (because it's not on my list of installed progs), nor can I re-install it , because it is not on the list of 'available' apps.
What am I doing wrong?
Thanks
