Cannot install Abaqus 2020 Gold-AllOS on Windows 10 Pro (64bit) because "This media is not for Windows operating system". What is wrong?

Hi 3ds community,

I am trying to install Abaqus 2020 Gold on my Dell Precision 7820 Workstation.

After downloading and extracting all four 2020.AM_SIM_Abaqus_Extend.AllOS.tar archives I am trying to run the \AM_SIM_Abaqus_Extend.AllOS\2\SIMULIA_EstablishedProducts\Windows64\1\Setup.exe

I always get the error message "This media is not for Windows operating system" although I am using Windows 10 Pro 64bit (1809, version 17763.1397). Not the newest version, but that is the newest version I can get within my company.

I have tried to run it in compatibility mode and with admin rights, same results. After googling this error message I have also tried to run it via cmd as Setup.exe -nosystemchecks, but no luck, same error message.

I did not have this problem with Abaqus 2018.

Can anyone help me with this problem?


Thank you and best regards

Markus
