How to register .DLL files in Windows 8 64-bit OS?

Question

I searched everywhere but found no result on how to register a .DLL file in Windows 8 64-bit . See my this wuestion too where I tried everything and then someone said that I have to register .DLL files. But how?

Answer 1

Only COM servers can be registered, glut32.dll is not a COM server.

A standard mistake is copying a 32-bit DLL into c:\\windows\\system32. They need to be copied to c:\\windows\\syswow64 instead, the home for 32-bit executables on a 64-bit version of Windws. In general certainly best to avoid, messing with the Windows directories is always a mistake. Copy the DLL into the same folder as your EXE instead. Best done by a post-build event in your project.

Answer 2

Make it simple, add via Windows Desktop GUI:

1) Go to "Control Panel" -> "System" -> "Advanced System Setting".

2) At the "Advanced" TAB press on the lower right the button -> "Environment Variable".

3) Add any path you want to "Path" variable, make sure to put at the end ";".

4) re-start you computer.

Done :-)

From the cmd line, you can view the "Path" values by typing:

echo %PATH%

On Windows 8.1 Pro:

1. Copy xxx.dll file into the c:\\windows\\System32 folder
2. Right-click on "Command Prompt" and select "Run as Administrator"
3. Then register the file: regsvr32 c:\\windows\\system32\\xxx.dll
