Hello and thanks in advance for any help. I'm using Opera 12.16 on a laptop running Windows 7 Home Premium. When I manually check for updates I receive the message "You are using the latest version of Opera". However, the Software Updater in avast! Free Antivirus indicates that there's an update and, when I click on the link, I'm sent to "http://www.opera.com/computer" where clicking on "Free download for Windows" offers a download of "Opera 18.0.1284....tup.exe". The changelog shows that versions 15-18 have been released yet my 12.16 is up to date? Also, when I installed version 18.1284 it didn't recognize that there's already version 12.16 installed but it still installed in the same folder, C:\Program Files (x86)\Opera, only with "launcher.exe" instead of "opera.exe". I didn't dig much deeper but I'm thinking that "Stu'sOperaSettingsImport&ExportTool0.993 might get a bit confused if put to use, and I'm not really in the mood to manually tweak all of the customizations in the version 18 install, let alone sort through the mess of two versions installed in the same folder, so I uninstalled version 18. Can some kind soul please offer clarity? My brain really itches due to the confusion; any scratches much appreciated .
