Or, you can keep them around if you're keeping other versions folders just in case. If everything works fine, you can then also delete all the files if you want. * In the version folder you're keeping, if you want to stop it from updating, rename operaautoupdate.exe to operaautoupdater.off. You can also delete "installation_" and "installation_" if they're present. You can also delete the "old_status" folder. User the text editor's find-and-replace function to find all instances of the current version and replace them with the version that matches the folder you're keeping. * Edit "installation_status.json" with a text editor. Prefix their names with ```off``` for example. * Delete all the version folders you don't want and keep the version you want to roll back to. So, if the version you want to roll back to is still present, you can do the following (while Opera is closed).
OPERA FOR OLDER MAC INSTALL
There might be even older version folders left in the install folder too. This means the previous version is still there if you want to use it. When Opera updates, it leaves the older version folder and the older launcher.exe behind.
OPERA FOR OLDER MAC WINDOWS
Windows (Rollback to previous version stored in installation folder):
OPERA FOR OLDER MAC UPDATE
That Opera will also update to the new version, which will allow you to test whether the newest version is stable or not. Then, whenever you want to check for updates, just load launcher.exe in the "Opera Stable Update Check" folder to load that Opera and goto ```opera://about``` or ```opera://update```. Or, if you really want to, you can launch the installer, click "options", set "install path" to a folder named "Opera Stable Update Check" on your desktop (or wherever), set "install for" to "standalone installation", uncheck "import data from default browser", and install. For example, you can subscribe to the page's RSS feed. If you need to check for new versions of Opera, you can monitor. Then, launch the installer via the shortcut instead.Īnother option to disable updates is to add the ```OPERA_AUTOUPDATE_DISABLED``` environment variable (value for it doesn't matter) to your system. Then, you can right-click on the shortcut and goto "properties" where you can then add -launchopera=0 to the shortcut's command. Instead of using a command prompt, you can right-click the installer and create a shortcut to it. Then, Opera shouldn't start after installation so you don't have to worry about kill the updater before renaming it. Opera_version_Setup_圆4.exe -launchopera=0 To make it a little bit easier to rename the updater, launch a command prompt and ```cd "path to directory the installer is in"``` and launch the installer like this: You won't even be able to check for new updates via ```opera://about``` or ```opera://update```. There, rename opera_autoupdate.exe to opera_autoupdate.off. Then, go into Opera's install directory in the version folder. If it is, select it in the task manager and end task on it. Then, immediately check the Windows Task Manager to see if Opera's updater process is running. As fast as you can, as soon as Opera launches (where you can see the X for its window), close Opera. If you don't want Opera to automatically update to a newer version, you'll need to disable the updater.
* Launch the installer, click "options", adjust all the options and install.
