-program database manager mismatch; please check your installation
+> program database manager mismatch; please check your installation
 
 A program database file (.pdb) was created using a newer version of mspdb*XXX*.dll than the one the compiler found on your system. This error usually indicates that mspdbsrv.exe or mspdbcore.dll are missing or have different versions than mspdb*XXX*.dll. (The *XXX* placeholder in the mspdb*XXX*.dll file name changes with each product release. For example, in Visual Studio 2015, the file name is mspdb140.dll.)
