Cannot Install Software onto Windows 10 machine - Microsoft Community

my windows 10 machine stopped allowing me install/upgrade software (e.g. java, itunes, etc.).   won't allow me uninstall applications (e.g. adobe products).    1 of errors says there's installer running; when check task manager i can see windows installer , windows installer (32 bit) processes running.   i've tried "end task" each of these restart after 30 seconds or so.  happens after restart too.   same goes when kill msiserver service. 

any suggestions on how solve problem? 

thanks!
