Final Quality Update - 10.0.29 internal errror 500 opening FinOps

After applying the package XX the D365 Finance and Operations environment might not work. The error you receive will be a internal error 500. 


In the event logs there might be a Web event with a warning saying that it can't load System.IO.Compression. 


The solution to this issue is to open the <drive depending on vm>:\AOSService\webroot\web.config look in the assemblies. It will most likely have a duplicate line for System.IO.Compression.


Remove the <add assembly="System.IO.Compression" /> line. Perform a iisreset and it should solve the issue.
