I don't use Opera, so I can't advise on what version to use. The error message indicates the possibility of corruption of a file, probably an exe or dll. It usually means that the program has tried to write to a space in memory that "belongs to" another program or to another process in the same program.

Since the same error message can be produced by something other than the program that's running, (e.g. by Windows or your AV) reinstalling is sort of a "shot in the dark" procedure. It would be a reasonable thing to do, if you can't find something else to blame.

If you have an uninstall for Opera, it is normally recommended that you uninstall before you reinstall. Many "installation manager" programs will not overwrite a file that's already there, so a corrupted file may not be replaced by reinstalling over an existing installation.

The "software manufacturer" would be the "Opera people" - if you can identify an entry into their support facilities. They may have something posted, or a place where you can send questions. They may also have a "user group" where you can look to see if others have had your problem.

Since all browsers are vulnerable to virus attacks, they quite possibly have a download link where you can update your current version, and/or get a newer version.

Perhaps someone who knows more about Opera will offer advice on how to get to them.
