A Windows application may fail before its main window appears and show a message that VCRUNTIME140.dll or MSVCP140.dll is missing. The filename looks specific enough to invite a quick search and a one-file download.
That is usually the wrong recovery model.
These DLLs belong to the Microsoft Visual C++ runtime family. The safer fix is to identify the failed architecture and repair the supported runtime package, not to copy an unknown DLL into System32 or the application folder.
Start by recording the exact error
Take note of:
the complete DLL filename;
whether Windows reports “missing,” “not found,” or “unable to start correctly”;
the application path;
whether the failure appeared after an update or a clean install;
the Windows system type.
VCRUNTIME140.dll, VCRUNTIME140_1.dll, and MSVCP140.dll are related, but they are not interchangeable names for the same file.
Check whether the application is x86, x64, or ARM64
