Control Expert 15 returns error 'mfc140u.dll is missing' when starting

Control Expert returns the error 'system error: mfc140u.dll is missing' when trying to start.

This error will occur if the mfc140u.dll file already exists on the PC and it is of a newer version when Control Expert is installed.  The 'mfc140u.dll' file is part of the 'Microsoft Visual C++ 20xx Redistributable ' libraries that gets installed during the Control Expert installation process.  Per Microsoft rules, a software installation is not allowed to overwrite an existing version of a Microsoft '.dll' with an older version.  This rule prevented the
proper installation of the required  'Microsoft Visual C++ 20xx Redistributable ' libraries.




The specific version 'mfc140u.dll' file is essential for the registration of other '.dll's that are included with Control Expert.  As a result of this, the error could also be accompanied with the following error:



To resolve the issue,

• Rename the existing .'mfc140u.dll' file.
• Uninstall Control Expert.
• Reboot the PC.
• Reinstall Control Expert.
