Internet Explorer 11.*.  Multiline will not work with Internet Explorer 64-bit.

Since January 12, 2016, Microsoft ended support for older versions of Internet Explorer : https://www.microsoft.com/en-us/WindowsForBusiness/End-of-IE-support

In the Tool/Internet Options menu, check that the (default) parameters are properly selected:

Level of security for secure sites (trusted sites):

• Medium
• Uncheck “Enable Protected Mode”
• Click on "Custom level ... ", under "ActiveX controls and plug-ins", disable"Allow ActiveX filtering"

 
Advanced Security parameters:

• Deselect option Do not save encrypted pages to disk
• Deselect option Empty Temporary Internet Files folder when browser is closed
• Deselect option Use SSL 2.0
• Select Use TLS 1.0
• Select option Use HTTP 1.1
• Select option Use HTTP 1.1 through proxy connections

Additional toolbars in Internet Explorer that are "not" originating from Microsoft often cause problems with MultiLine (and other online applications) and slow down the system. You should therefore uninstall these toolbars in advance.

• Add the sites you need to work with in the “Trusted Sites” list of Internet explorer; for this category only, uncheck “Enable Protected Mode”.

Remark: Please be aware that certain local or domain group policies (GPO's) can overrule the trusted sites settings of your internet explorer. If you use GPO's, please make sure that the sites are added here:
for 32 bit here:
HKLM\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap
or for 64 bit here:
HKLM\SOFTWARE\Wow6432Node\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap
