I tried literally every single thing in this thread (and many others) multiple times over the last couple months and this is what finally worked. Thank you for posting! Fingers crossed that it continues to work!
folks, if all the compatibility stuff doesn't work for you, this is the solution!
This worked for me as well. Double clicking the setup file or running it from the browsers download manager (chrome) gave me the said error. Locating the file in the download folder, right click and choosing run as administrator gave me the same error as well.
