I just did a manual update of Adobe Flash to version 220.127.116.11. I usually do the automatic update when I'm prompted but I was doing other updates so I decided to do it manually. I looked in the Windows\SysWOW64\Macromedia\Flash directory and now there are two versions in the directory, 18.104.22.168 and 22.214.171.124. The install did not automatically uninstall the previous version like the automatic update does. Is is OK to just delete the 169 version files from the directory? Thanks.
