We've noticed that some systems may not launch Serato DJ Pro or Serato DJ Lite, and will advise that a .dll file is missing. At this point it appears to be mostly VCRUNTIME140.dll, but there may be other similar, missing dll files causing the error.
To resolve this, please install the Microsoft Visual C++ 2015 Redistributable package from the link below: https://www.microsoft.com/en-us/download/details.aspx?id=52685
NOTE: When downloading the package, you will be asked to choose a package. x86 is for 32-bit versions of Windows, and x64 for 64-bit versions.
If, after successfully installing the package above, you are still seeing a message about a missing DLL library, please try installing the latest Windows updates. If issues still persists, generate a DXDIAG report, following the steps here, then get in touch with Serato support, here
