Q: When I start the monggoDB database, an error occurs: The reference program cannot start normally (0xc000007b). Please click "OK" to close the application program. How can I solve this issue?

A: It is caused by the lack of libeay32.dll and ssleay32.dll. The decompressed version of mongoDB does not have these two libraries as the installed version. You can copy the two missing libraries directly from the installed version to the decompressed version.
