Couple of things
1) This is very old version of Qlik, Consider upgrading it.
2) Make sure the user uses same IE pluggin as that of your server version.
3) As it is working for some users I suggest to check their IE version and install the same for those users you have an issue with.
Let me know if that worked.
Thanks a lot for your answers. We will consider upgrading soon but not at the moment.
I am checking two different PCs with same version of IE (IE 10)
One of them is able to install and use the plugin and this is showing up in Manage Add-ons
Whereas in the other one, installation of plugin was successful but when I go to Manage Add-ons, the extentions is not there:
Any idea why?
It could be that it is not registered which could happen if the installer didn't have enough privileges.
You could try running a command prompt as administrator and then registering the OCX manually. First find where QlikOCX.ocx is located on disk, and then run
If on 32bit OS:
regsvr32 "C:\Program Files\QlikView\QvPlugin\QlikOCX.ocx"
Or, if on 64 bit OS:
"C:\Windows\SysWOW64\regsvr32.exe" "C:\Program Files (x86)\QlikView\QvPlugin\QlikOCX.ocx"
ok, that's a pity. It might be worth just doing a quick test upgrading to the latest plugin on the machine which has the problem just in case it is something which has been fixed already.
Could also be a compatibility issue with the other add-ons. See if there are any add-ons on the bad machine which are not on the working machine and if so, disable them temporarily.
