Not sure if you can help with this .
Which version of Windows are you using? I know Microsoft made a change, but I was under the – maybe wrong – impression that all current Windows versions had the files they needed to run EditVoicepack.
Please try installing the .NET Framework runtime manually from here:
Download .NET Framework 4.8 | Free official downloads (microsoft.com)
You need the runtime, not the developer pack.
Once it is installed, please try running the EditVoicepack installer again.
