My opera portable stopped running. It does not even open. It doesn't show up in the task manager. All my other portable apps work. The PA launcher has been updated. The Opera version was uptodate the last time I used it. I have also reinstalled it. It simply does not run at all. I even tried a brand new portable install on my desktop, and it will not run. Any thoughts? Would a lack of admin rights prevent it from running? My IronPortable runs fine on the same computer.
