reinstalled net framework.

Audacity 2.3.0 requires "Visual C++ Redistributable for Visual Studio 2015 " which may not be present on old Windows systems. You can get it from here: https://www.microsoft.com/en-ie/download/details.aspx?id=48145

installed it, still the same error.

Reboot the computer.
If that doesn’t fix it, see this topic: https://forum.audacityteam.org/viewtopic.php?f=50&t=102054&hilit=0xc000007b
