Quotehttps://efmer.com/boinctasks-js/boinctasks-js-download/shows 1.11 with instructions to install, because BOINC itself isn't in the store they refuse to accept BoincTask Js, so sideloading is the only option.
With so many huge changes in version Properties stopped working and elapsed time ready to report, added to the list
If you find anything else let me know.
Even with sideloading enabled (which BTW, is now labelled "Install Apps from any source including loose files") it still errors out and refuses to load.
A rename to .RAR and a manual extract to a new directory in C:\Program Files does, however, work.
