Tons of errors while running ngen.exe on MTD

[Sabine Ludewig1709156713]

Hi everybody

I'm wondering if this is normal.

We use Citrix Optimizer with .Net Optimization (ngen.exe /update) and it returns tons of error messages like

- Failed to load the runtime (Exception from HRESULT: 0x80131700). Assembly will be compiled once the correct runtime is installed.

- Warning: Syste,.IO.FileNotFoundException: Could not load file or assembly 'AssemblyName' or one of its dependencies. The system cannot find the file specified while resilving 0x100000f

 

No unusual software is installed, just Office, Notepad++, Keepass and such

Environment is  Windows 2019,  CVAD 2203 LTSR incl. PVS

 

Is there anything I can do about these messages or just ignore them?

 

Thanks for your opinion
