When using the DSpellCheck plugin, it seems that I must use "Settings" to re-download the dictionary every time that Notepad++ is restarted. This is true irrespective of whether setting specify "For All Users" or "For Current User". I think this started with upgrade to 7.5.6. Is it possible to revert back to previous version?
I decided to quit using the portable app version as installing version 7.5.5 separately works fine right out of the box. Also since Notepad++ appears to be inherently portable there isn't much benefit to using portable app version. In fact, this experience resulted in the portable app desire to update an app that was working fine causing lots of unnecessary problems. Portable apps platform should consider figuring out a way to undo such an update.
