Installing downloaded Audacity 2.2.1 fails

I have Audacity 2.1.3 installed on my Windows Dell XPS 13 2N1 laptop computer operating under Windows 10x64 on which I am the Administrator. I have downloaded Audacity 2.2.1 installer file and proceed to install, which shows C:\Program Files (x86)\Audacity. I get a prompt message that this folder already exists, but I choose to proceed, which eventually opens the window: Setup - Audacity; Installing - Please wait while Setup installs Audacity on your computer. There is also a status bar window, which is blank. I have waited several hours without any “progression” change to the status window. Further, I cannot “Cancel” this operation. My only option is via Task Manager to End Task. I would appreciate guidance/help.
