Flexnet application server issue after upgrading OS from 2012 to 2016

[GopalRaghvani]

After completing a OS upgrade from 2012 to 2016, the Flexnet 2020 R2 application is non responsive.

It seems to be a ISS possibly web.config issue.

Has anyone got an experience with this?

Any help is appreciated.

 The database OS upgraded fine.

In-place migration sounds like a terrible idea. Have you tried re-running the configuration script?

Tried that did not work. Slow server was caused by SCCM agent, System Engineer resolved it.

I get Compilation Error now.

I concur with @mfranz here - upgrading an OS in place is unlikely to be a recipe for easy success. The errors you're seeing here feel like they are related to the OS being upgraded, but configuration of various components still being set up for the old OS. I can't think of any reliable or robust way to work out what you may need to reconfigure in terms of software that is installed, or how to go about doing that reconfiguration, in order to get an operational system.

I would really recommend starting from a fresh OS install, and then install FlexNet Manager Suite prerequisites and components on top of that.

Hi,

Could you verify the latest .Net version is installed on your server? I had similar issues and had to install a newer .Net version

Issue was with Web.config missing a entry.

The error was fixed by adding entry to System Folder\Flexera Software\FlexNet Manager Platform\WebUI\Web.config

Add --> <add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

Server Engineer found fix from:
