New problem with Internet Explorer in Windows 10

Problem

Michaela reported:

I have problems with SuperMemo 17 as it keeps displaying the following message:

SuperMemo requires Internet Explorer ver 6.0

You are currently using Internet Explorer 0.0

FAQs suggests updating IE. However, I already have IE v 11 installed and SM was already working for months. The problem is present in all collections.

I tried re-installing Supermemo and IE but the same error pops up. What else could I try?

Suggestion

Comment

The problem comes from incomplete or incorrect installation of Internet Explorer. It may also result from incorrect installation status reporting.

The following property is incorrect: Internet Explorer MSHTML Engine: Trident ver. 0.0.0

It should similar to this: Internet Explorer MSHTML Engine: Trident ver. 7.0.0

It should also be followed by agent setup. For example: IE Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 10.0; WOW64; Trident/7.0; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.30729; .NET CLR 3.5.30729)

Reinstalling SuperMemo will not help. Updating Internet Explorer and/or Windows Update might help.

Answer

This may occur if you are a client of Windows Server with insufficient rights

Technical

The IE version protection dates to the times when IE might be missing from Windows. The protection was removed from version 18.041. This would tie SuperMemo 18 to Windows 10 (potentially causing problems in older Windows when there is no Internet Explorer - problem not reported thus far)
