A list of deprecated features docs.microsoft.com/en-us/sharepoint/what-s-new/…

Putting this link in as a holding comment for now whilst I explore different solutions whitepages.unlimitedviz.com/2018/08/…

Although it got past the issue with the language with the updated svrsetup.dll. It does ask me for a product key. However, the MSDN subscription states the key is not required. I am guessing the key info requirement is in that svrsetup.dll.

I also had a svrsetup.dll in the updates folder. It looked like the wrong one. I redownloaded from docs.microsoft.com/en-us/sharepoint/troubleshoot/… and it seems to work now. I will write this up.

Without that wssetup.dll, the installer displays the This product requires Microsoft .NET Framework 4.5.

That worked for me xristian. I set: <compilation batch="false" debug="true" batchTimeout="600" maxBatchSize="10000" maxBatchGeneratedFileSize="10000" /> and <customErrors mode="Off" />
