Oracle10g: Error encountered when registering mfc40.dll,please run regsvr32.exe to register

problem¶

When installing Oracle, I keep getting the error:

Error encountered when registering mfc40.dll,please run regsvr32.exe to register

That is, an error is encountered when registering mfc40.dll. After the installation is complete, please run regsvr32.exe to register this file; this problem causes a problem with the service configuration of the database, and the service is equipped with the database but cannot be accessed; the solution is as follows:

solution¶

1. Win+R, type cmd to open the command prompt
2. Enter regsvr32 /s mfc40.dll to register the DLL file

This way, the problem is solved!
