Glad it worked. Thought it was worth a try.I just tried that installer over my K.Plus 21.5c (in my lap) and it went fine, it seems it's a K.Standard installer, but never mind, since the installer detected my K.Plus / KSCloud licence installed and it auto converted to K.Plus 21.6

I looked there earlier and totally missed that in the sub nav. doh!
Now you can switch to Kaspersky Plus from Kaspersky Security Cloud and Kaspersky Total Security.
