How to Manually Register DLL in Windows Vista

Register DLL and Executable Files Manually
1. Know the path and file names of the files you wish to register.
2. Click 'Run' from the Start menu.
3. Type the following into the field provided: regsvr32 '[path]\NameOfFile.extension'. [path] is the directory where the file is located. For example: C:\ The extension will be .dll
4. Look for the dialog box that says 'DLL Register Server in C:\Program Files/Common Files/Microsoft Shared/MSI Tools/mergemod.dll succeeded.' Click 'OK.' Your file is successfully registered.
5. Type '[path]\NameOfFile.exe' /REGSERVER' to register an executable file.
6. Launch the program manually if it does not launch automatically, in order to check and see if the registration was successful. Remember that without certain files attached to the registry, the program will not run successfully on Windows Vista.
