Windows 10 Anniversary may impact Microsoft .NET 3.5 preventing access to Sage 50 Accounts


Following Microsoft’s recent Windows 10 Anniversary update, some Sage customers have reported that they are unable to log in to Sage 50 Accounts after installing the update.

This may cause one of the following errors or issues:

  • The message 'You have entered an invalid password' appears
  • The message 'Unable to register datasource' appears
  • Sage Accounts freezes on the splash window or the splash screen flashes and disappears - this is the window that appears as the software opens.
