Updater aborts on a less severe error - why not continuing?

On download fails, the updater should just continue and show download errors at the end. It doesn't sound like that was the case here, though. A what point does the error occur and what is the exact error message included. You can CTRL-C with a messagebox shown to copy the text in any standard Windows messagebox. A pro tip is to always include the exact error when submitting a bug report to anywhere so the developer can determine the exact point in the code an error is happening.

Are you absolutely sure the updater stops and processes nothing else? The logic in the actual code doesn't do this. Whenever that specific error message is displayed, it stores the error and sets the bit for displaying it at the end, so it should continue updating anything else and display the error at the end. Is it a messagebox window or within the actual updater form at the end? The only thing I can think of is that your antivirus then kills the updater's ability to do stuff once it has its false positive error. I've never encountered that from a regular commercial antivirus product but I don't have much experience with enterprise antivirus.
