Apology first: Trying to ask relevant question BUT am 70+ and still learning.
Problem: Recently downloaded RStudio-2022.12.0-353. Cannot open it. All attempts lead to re-installation window.
History: Downloaded new version on advice that my previous version (successfully used) was outdated.
Possibly related problems: Tried to have shortcut icon placed on Desktop. However, click on desktop icon leads back to installation option.
Further apology: Tried to find related questions before sending this but have not yet found a workable match.
Sincerely grateful for help.
