Why does error 126 occur?

Error 126 often occurs at runtime, that is, when you are trying to run some application. The reason behind this error is the unavailability of some DLL files associated with that application. So, to run that file, it is important that you specify all the paths of the different DLLs because connecting to the database requires these files. Some common databases are: the Oracle ODBC driver, the Microsoft Oracle driver, and the WinSQL Oracle driver. (Good explanation)

The second reason for error 126 is DLL corruption. The DLL file may be corrupted due to some malicious application such as malware and virus.
