When unzipping a fresh copy of 2.3.7 Complete for a new Windows 10 laptop, I encountered an error when it reached 99% stating 'Destination Folder Access Denied' (yet I was on the admin profile) and clicking Try Again would just send it into a loop (see screen shots 1 & 2).
To resolve this: download 7-Zip (http://www.7-zip.org/download.html) to extract the files but FIRST create a folder called AXtime on your C:/ drive and extract into there. BAM! No errors, works like a charm! (see screen shot 3)
