Either way, you should be able to solve it by reinstalling Chrome.
Head to Start menu > Settings > Apps > Uninstall Chrome.
Head to the official Chrome download page and download it again. (The one button installs the 64-bit version these days, so no hunting around required.)
Many thanks for the support. Sorry about the delayed response. Followed your suggestion and have now successfully installed Chrome on my win 10 pc. Many thanks again, John D.
