I had Browsercheck plugin installed for years, but probably after update to Chrome 42 strange thing happens. When I try to access https://browsercheck.qualys.com/, install plugin page appears, after clicking on install, plugin seems to be successfully installed, but "Install Plugin" button change color to grey and nothing else. When I reload page, same situation happens - again Install Plugin. Plugin removal and reinstall doesn't help. Same behaviour we have met on most of our laptops. OS is Windows 7 64 bit. Plugin in other browsers on same notebook works fine (tested IE + FF).
Has anyone met similar experience? Any recommended solution for this problem?
