Hi @Charles AllenThis could be related to Named Printers. Named Printers stores binary printer settings information that is specific to the printer driver installed. Changing OS is very likely to change the printer driver so that the stored binary data is no longer valid. Attempting to use this binary data from an old driver with the new driver is very likely to cause instability.I documented this when I wrote the following KB article:https://support.microsoft.com/en-au/help/909739/error-message-when-you-try-to-start-microsoft-dynamics-gp-on-a-computeDavidOriginal Developer of Named Printers.
