Hey everyone

We’re somewhat worried about the minimum OS requirements for DF 19.1. In the help: Deploying Applications -> Installation and Environment Guide it’s stated:

Supported Operating System and Browser Environments
DataFlex 2019 Studio, Windows Client and WebApp Server are supported on:

  • Windows 10
  • Windows Server 2019 (including x64)
  • Windows Server 2016 (including x64)
We would like to migrate our web applications to 19.1 to use the new features, but not many of our customers are on Windows Server 2016, let alone 2019. We have web applications in 19.0 deployed to OSs as far back as 2008 R2. Many of our customers are in the public administration and have budgetary constraints preventing them from upgrading servers or software so frequently.

I installed DF Web Server on 2008 R2 and 2012 R2 to make some tests. In 2008 R2 the installer cannot register dfedit40.dll correctly and the web application cannot load the IIS module WasHttpMod.dll, making the app pools stop, even those whose applications don’t have the module registered for them.

In 2012 R2 DF Web Server installs fine. But when testing with the WebOrder examples, reports don’t work, the COM ActiveX does not get properly installed.

Since we have to make a decision about waiting for a while in 19.0 or maintaining both 19.0 and 19.1 codebases, I would like to know if there is something like a list of features that may or may not work per OS below Server 2016.

Thanks very much
