WMS 3.6 requires version 4.2.17 of MongoDB

When trying to upgrade from 3.5.2 to 3.6 I got the error message: 
"WMS requires version 4.2.17, Please make sure your Remote MongoDB is 4.2.17 and retry the installation."

I downloaded the correct version from this link.
https://downloads.mongodb.com/win32/mongodb-win32-x86_64-enterprise-windows-64-4.2.17.zip

Stop the service "Dell WMS: MongoDB" ("Dell WMS: Tomcat Service" will be stopped automatically)
Extract all the content from the zip-file into the directory where "mongos.exe" is located. If you are unsure where this is, look at the Path to executable under the General tab of the "Dell WMS: MongoDB" service.
Example: "C:\Program files\DELL\WMS\MongoDB\bin\mongos.exe" 

If you only extract mongos.exe and not the rest of the files the service will be unable to start since it's missing some files. (I couldn't start the service because libsasl.dll was missing)

Start the stopped services manually or do a reboot of the server.
I was then able to run the 3.6 installer and upgrade successfully.
