Here is a document to assist with enabling "npapi". You will need to relaunch the page after.
could not see a link or document. Where can I find it ?
I searched in the internet and found quite some hints reagrding npapi and Google Chrome. But on my machine runs Internet Explorer version 11.0.9600.17801. Ialso found hints, that npapi is not supportedanymore by internet explorer.
Does it mean, that the console is unly running on Chrome browser ?
IE 11 is not supported as the added security blocks the ability to configure software packages. Chrome, IE 10 or Firefox should work. With Chrome you will have to use the workaround noted here : Unable to configure software packages after chrome update
FYI, in the latest updates to Chrome, NPAPI has been completely disabled, and the workaround is no longer an option. Firefox appears to be the only browser that works using the current version, and they have announced that they will also be disabling NPAPI by the end of 2016.
