I made no changes to my system, yet PA for the most part quit working. I get the popup message ...\PortableAppsPlatform\PortableApps\OperaPortable\App\Appinfo\Launcher\OperaPortable.ini is missing [Launch]:Program executable - what am I to launch?
I verified that the ini file exists and the permissions are good. It contains this:
I uninstalled and reinstalled Opera and got the very same problem.
I tried installing the IronPortable browser (new for me) and got the very same problem.
I tried running my existing PhotoFiltre app that I used just a few days ago and got the same problem. Same with PicPick. Nik2Edit is OK. GIMP same error.
