We have the same problem with QlikView 12 and Plugin.
The server is located in Germany. Our subsidarys in the USA and Canada - each are connected via a 2 Mbps leased line - complain of a very poor performance. Working with IE plugin is not possible in practice. With QlikView 11.20 SR1 the performance was ok.
If there is no other solution, we will do a downgrade to Qv 11.20 SR 13.
Downgrading to QV 11.20 will not be a solution, i've tried it without luck.
Meanwhile after i have published this tread i have had contact with some Qlik developers about this issue.
There answer was not so promising...
Apparently there is a known compatible issue with the IE plugin. They advised me to use the plugin only with IE 8 or IE 11 ( other versions of IE will provide problems ). The IE plugin will NOT be supported by Windows 10 anymore, in fact as they told me, it will disappear for Windows 10 in the future.
They strongly advised me to use the Full browser AJAX version instead.
Hope this helps you?
Thanks for your answer. Problem is that we have been working for 4 years with Qlikview and the IE plugin and for us the plugin has some features we need, but wich are not present in Ajax.
So, it will be very difficult to convince the user to use Ajax.
I thought so, that the downgrade means a reinstallation of the QlikView environment.
But on this way we gain time and we can prepare the user slowly on it.
Thanks and regards
This happens when you install a newer QVPlugin on top of an existing version. There is some sort of conflict. Remove all instances of the plugin and reinstall.
