Update to Progress OpenEdge 12 requires .NET framework 4.7 or higher

With version 005.082.000, we have updated to Progress OpenEdge 12. This brings our database server and application server back up to date with the latest technology. OpenEdge 12 requires at least .NET framework version 4.7. During the installation of version 005.082.000, a check is performed on this. The installation is aborted if too low a version is found. The MKG environment is available again afterwards.

Error situation (MKG version update dialogue):
STATUS (76): Busy checking .NET framework version. (7000)
ERROR (76): Minimum .NET framework 4.7 must be installed. Current .NET framework is 4.6.2 (-7002)

Solution:
Ensure that .NET 4.8 is installed on the MKG server. On the MKG server, run the following installer that installs .NET 4.8:

After installation, a reboot of the server is required after which the update of version 005.082.XX can be restarted
