The error message is a common hurdle when running legacy database applications on modern Windows systems. It occurs because the program was built using Microsoft Visual FoxPro (VFP) but cannot find the specific runtime DLL files required to execute its code. Why This Error Happens
The error "Cannot locate the Microsoft Visual FoxPro support library" is intimidating, but it is rarely fatal. In nearly every case, it is solved by running an official Microsoft redistributable installer ( vfp9sp2runtime.exe ) and rebooting your PC.
Some VFP applications embed a "manifest" that demands a specific version of the runtime (e.g., 9.0.0.3504). If you installed a slightly different version (e.g., 9.0.0.5815), the application refuses to load it.
If you are a developer maintaining a VFP application, do not rely on end-users to install runtimes manually.
