[BizTalk] Regsvcs failed for assembly MQS.dll while installing BizTalk 2016 feature packs or cumulative updates

Problem:
You may encounter the following error message while installing BizTalk 2016 feature packs or cumulative updates.


« Error 5003.Regsvcs failed for assembly C:\Program Files (x86)\Microsoft BizTalk Server 2016\Microsoft.BizTalk.Adapter.MQS.dll. Return code -2146234013 »


Cause:
Unknown. A case has been opened at Microsoft for this issue.

Solution:
We didn't really find a solution to this problem. We have been able to avoid the issue by:
1. first performing a minimal installation and configuration of BizTalk 2016 (BAM was not installed)
2. we then installed the Feature Pack 2 of BizTalk
3. Finally, BAM and its prequirements were installed and configured

Normally, there is no link between BAM and the MQS adapter. But in reality, when performing the installation in the order mentioned above, we were able to sucessfully install the BizTalk feature pack.
