Since the upgrade we have a problem to start the USoft binder and the following error message is shown: The code execution cannot proceed because mfc140u.dll was not found. Reinstalling the program may fix this problem. Could it be that there is a problem with the registry?

The mfc140u.dll is part of the Microsoft Visual  c++ 2015 redistributable. Normally it is installed along with a USoft installation. The redistributable vcredist_x86.exe / vcredist_x64.exe setup file you can also find seperately in the redist/Microsoft/ folder.

For 32 bit versions of USoft , the C:\Windows\SysWOW64 directory is used to locate mfc140u.dll.

For 64 bit versions of USoft , the C:\Windows\System32 directory is used to locate mfc140u.dll.

If for some reason is missing, you may need to reinstall the Microsoft visual c++ redistributable by launching the above setup file or reinstall USoft. You can also find the currently installed Microsoft Visual  C++  via the "Apps and features" configuration page of Windows. If the Visual C++ redistributable is installed, it will be listed here (including x86 or x64 and version number details).
