Rolled out the GA release for NPM 11.5 this morning and was greeted by the error below.
A call into support (even though we *did* roll this in dev first) revealed a possible problem with the installer. Support moved the file above (\Solarwinds\Interfaces.Discovery\Solarwinds.Interfaces.Common.dll| out of the folder and re-ran the configuration wizard. Install continued without an issue.
Heads up though -- I did have an issue with the ImportMapBatch process but clicking on 'Close the Program' allowed it to continue without a problem. (As we don't leverage maps it wasn't a huge deal, especially in dev.)
