Thought I should report that, as at 2018-04-08 1038hrs (NZT), all the download files of CCenhancer v4.5.2 from different sites (e.g., singularlabs, MajorGeek)would seem to be corrupt/invalid (.exe and .zip).
The ,exe files cannot execute (Windows10 Pro).
In the .zip files, Windows cannot open them, and 7-zip reports corrupted data and invalid header. Extracted .exe files (using 7-zip) cannot execute.
NOT getting any virus warnings.
Hope this helps or is of use.
