Great job Dennis and thanks for sharing your solution.

Thanks for sharing the information. Would you mind telling us how you confirmed that the uninstaller did not completely remove the application? I'm curious to know if this is specific to the OS on the device or if it's a universal issue with the uninstaller. As for the tool you mentioned, is it the Windows Fixit utility?

After we restarted the Microsoft Surface, Sage 300 ERP remained in the Control Panel add/remove programs and you could go though the uninstall again and each time , it would still be there.

Of course, you could re-install and only one Sage 300 ERP installation would be listed but Windows was not removing the registry keys.

Sage 300 ERP 2014 Pu would open but you would error when you logged into a company.

I used Advanced Uninstalled and it showed me the keys to remove. Then I checked them off to be removed. Restarted and things went smoothly; end of story.

I did not  try Windows Fixit.

Thanks Dennis. I've also seen that issue on a couple Win 8.1 PCs. We too were able to get Sage 300 ERP on Surface Pro working but it was only a quick test. We wanted to see a consistent behavior of Sage 300 between a regular Win 8.1 PC and Surface Pro but that's not what we've seen so far. I then requested our QA team to include Surface Pro in the testing so it can be officially supported.
