Sonar Home Studio on new device; VST scan problem

EDIT: all solved BUT, now I was trying to install a new vst plugin with, unlike Kontakt, it doesn't find. I told him to consider also the folder (programs x86) in wich the program has been installed, and now at every automatic vst/plugins search it alwasys freezes on certain .dll files and it doesn't even let me change options to select the folders to search into, as it says "another search alreary running"...and, since it always freezes at the same point, it is "arlready running" forever, of course. I' ve also tried to copy and paste the .dll files in another temporary folder, but then Sonar gives me another error back. Is there any way to stop automatic vst search, in order to change options, delete programs x86 folder from search option, and then re-install the vst in the "vstplugins" folder and start a new search there?

I have 64 bit Wondows 10. Also version of what?

Thank you very much! This time, I don' t  really know how, it found the plugin out of the blue without changing anything (except putting the plugin in the "vstplugin" folder, wich I previously tried anyway), but now I will know how to fix this next time :) Thank you very much!
