When upgrading Opus, almost every time, the installer stalls on dopusrt.exe, saying "cannot create a file when that file already exists".
Usually I click "ignore" and that seems to work.
Sometimes I backup settings, uninstall, reinstall---the long way home.
Is clicking "ignore" okay?
I would click Retry instead, otherwise the installer probably won't replace dopusrt.exe with the new version and will just leave the old one.
The one time I've seen that happen, Retry worked. Not sure what the cause is; maybe anti-virus blocking the file the first time it scans it or something? The installer should shut down dopusrt.exe and so it's usually one of the easier files to replace (shouldn't even need a reboot, unlike the DLLs).
Thanks!
