Download from PortableApps.com. Version 12.18 for Windows, Multilingual 13MB download / 40MB installed. Notes| Details. Opera Portable Legacy 12 can run.
I just checked my opera version 12.17 to see it needed updating. It said there was an update available. I clicked on the link to download and install it. It never really seemed to start the download and said there was an error (unfortunately I did not write the error down, but it said it could not automatically recover from the error and there was now a button that said 'manual install'. I clicked on that but it gave the same error. I closed opera and reopened it and went to check for updates and it now said my version of opera was up to date. That is when I pulled the version number 12.17 (32 bit). Since it acted so weird, I used another browser to check for the latest version of opera. I downloaded and installed it (that is what I am using here) and it now shows that I am using:
Version: 25.0.1614.63 - Opera is up to date
Update stream: Stable
System: Windows 8.1 64-bit (WoW64)
Update stream: Stable
System: Windows 8.1 64-bit (WoW64)
What happened that my opera version 12.17 tried to update, failed and then told me my opera was up to date?
