Question : Cannot Register a DLL File

Hello Everyone,

I'm trying to register msxml4.dll
It was not in the System32 directory so I got it off of another system, put it in the directory, and it still won't register.

The error I get is LoadLibrary("msxml4.dll") failed - A dynamic link library (DLL) initialization routine failed.

I also tried loading the file through Dependency Walker and I get the following error.

LoadLibraryExW("C:\msxml4.dll", 0x0000000000000000, LOAD_WITH_ALTERED_SEARCH_PATH) called from "REGSVR32.EXE" at address 0x0000000100002522.

Answer : Cannot Register a DLL File

[19|20] means any character: 1, 9, 2, or 0 -- the vertical bar is redundant. The plus means one or more of the previous, so one or more of 1, 9, 2, or 0. The rest means exactly two numeric digits.

Try the following pattern instead:

1:	(19|20)\d{2}
