Reinstall the x64 redistributable package. Do not download individual DLL files from third-party websites, as this introduces security risks and version mismatches. 32-bit vs. 64-bit Architecture Confusion

Look at the architecture of the application, not your operating system. If you run a 32-bit legacy application on a 64-bit OS, you must install the x86 version of the Visual C++ 2008 SP1 Redistributable. If the application is native 64-bit, use the x64 package.
