The error message indicates that the installation is looking for a file (regasm.exe) in a specific location (C:/windows/Microsoft.NET/framework/v2.0.50727/) but cannot find it. This could potentially be due to missing or corrupted files in the .NET framework on your Windows 10 system. To resolve this issue, you can try repairing or reinstalling the .NET framework on your computer.
