Try, if you want, my InnoSetup Installer: -Installer only English/Spanish but is multilanguage -If you want Silent Install use /silent or /verysilent Regards... ;-)

Not need display hidden folders, you can put folder variables in Explorer Path bar directly, or use in WinRAR as by example Path=%localappdata% or Path=%programfiles(x86)% Have you tried my WinRAR sfx example...? Regards... ;-)

I always use my Windows PC as Admin user and UAC disabled from years, I don't like clik OK button every time... Only use Nod32 AV and uBlock Origin in Firefox, but all suspected and new programs are always tested first in VirtualBox... I repack all my programs to avoid junk inside and I haven't any infection by now... It's only my humble opinion... Regards... ;-)

Default install forder for Jdownloader 2 is %localappdata%\JDownloader v2.0 it's better use default folder to avoid problems with updates or configuration... I did a test in Windows 10 x64 Pro and works without problems for me with WinRAR v5.30 (I'm Admin User)... Try it if you want: Regards... ;-)
