Failed:verifying transcation

While installing mfix 21.4:
CondaVerificationError: The package for ucrt located at D:\Anaconda\pkgs\ucrt-10.0.20348.0-h57928b3_0 appears to be corrupted. The path ‘Library/bin/ucrtbase.dll’ specified in the package manifest cannot be found.

Hi. We have not seen this error before. It looks like an issue with your Anaconda installation. You have installed it to a system location D:\Anaconda, perhaps there is a permission problem?
You could try updating the offending package:

conda update -c conda-forge ucrt

or perhaps, update/reinstall the base Anaconda installation

I’d also like to know what OS you are installing on

Thank you ,the OS is win 10.
