Hellow,
I installing orchestrator prerequisites softwares, but I have issues with .net framework 4.7.2+ and url rewrite module.
For .net framework 4.7.2+, I cannot install it because a lower version (4.5) is already install on windows server 2016. In the registry my directory structure is different, missing the setup directory.

For url rewrite, I cannot download it because of SSL certificate issue from the source website. Has anyone encountered these issues and how did you resolve them?
Please,see the screenshots below.

I would review and if possible share your log file to better understand what challenges you might be running into.

What version of Orchestrator are you installing?

I can’t speak to where the Installer is trying to fetch the other packages from, perhaps if you review the log it will give an indication. In which case you could then import the certificate if you trust the source. As a possible alternative, you might try disabling IE Enhanced Security for Administrator even as a Test or Temporarily.

You can also download URL Rewrite 2.1 directly for Microsoft URL Rewrite : The Official Microsoft IIS Site and install it before running the Platform Installer.

What is the specific error you are getting when it attempts to install .NET Framework 4.7.2?

.NET Framework 4.x is compatible across the branch from 4.0 to the latest you have installed, if the install is newer than existing you should not have any issues installing it, if you are attempting to install a lower version, I believe it will prevent that.

You can grab the Offline Runtime Installer from Download .NET Framework | Free official downloads, but generally I would just go with the latest 4.8.1 if for nothing else security fixes.
