  • Hi ATerentjev,

    For your issue, we need to make sure whether the .NET framework is installed correctly, please take the following steps:

    1. Use .NET Framework Setup Verification Tool to verify the .NET Frameworks on your machine, you can download from here:

    By using it, you will find the log file under %TEMP% folder, see the first 15 lines and the last 15 lines.

    2. If the exit code != 0, it means that your .NET installed incorrectly, please first use .NET Framework Repair Tool to repair it,

    Best Regards,
