Problem resolved

Removed the 2020 R1 installation and IIS and started from the beginning.

All now up and running.

Thanks for all input.

Sorry for asking the obvious: When you configured IIS, did you enable the .NET Extensibility and ASP.NET features as documented in the "Installing FNMS on Premises" documentation?


Sorry, should have been clearer - this is an upgrade to a fully functioning 2019 R2 installation

and yes, all configured

Hi @Smitty987

Microsoft says: To resolve this problem, install the updated version of the Microsoft .NET Framework 4.5.2 Developer Pack. For download information, see Microsoft Knowledge Base article 2901951 .


Already installed.

Hi, I have exactly the same issue. Are you saying that you resolved the issue by completely removing the previous version of FNMS and also removing IIS, then carrying out a fresh installation of both?


Yes, started from the beginning - obviously removing IIS means you need to go through the pre-requisites to ensure everything is installed.

The only other thing I did was to rename the folders to FNMS so that the path when running the .ps1 file was shorter

i.e. FlexNet Manager Suite Installer 2020 R1\FlexNet Manager Suite\Support  - became FNMS\FNMS\Support

Good luck !

Hi, just wanted to add that this issue has been identified as a bug by Flexera (bug ID: IOJ-2128316).

It can be fixed by adding a line into the web.config <assemblies> section as per below


  <add assembly="DevExpress.Data.v15.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

  <add assembly="DevExpress.Printing.v15.1.Core, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

  <add assembly="DevExpress.Utils.v15.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

  <add assembly="DevExpress.Web.ASPxTreeList.v15.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

  <add assembly="DevExpress.Web.Mvc.v15.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

  <add assembly="DevExpress.Web.v15.1, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

  <add assembly="DevExpress.RichEdit.v15.1.Core, Version=, Culture=neutral, PublicKeyToken=b88d1754d700e49a" />

– to add – <add assembly="System.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>


After making the update to the web.config restart IIS to load the new config

Thank you for the valid workaround @michael_hoogen

The product team has identified a defect logged under FNMS-68929.  An KB article is also created for the affected user to apply the workaround.

I've checked our system and the 

"add assembly="System.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/"

line is already present in the web.config file.

Not sure if it was previously missing when \i was getting the error.
