Recently I ran into trouble when I discovered that vista restricts what can be installed into the system32 directory even though I am the administrator for this computer. It will not allow me to register dll files so I can use programs like wget globally like how programs "nslookup" etc are used. Keeps giving me this error.

Regsvr32: The module "C:\Windows\System32\libeay32.dll" failed to load.
make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.

The specified module could not be found.

Moving the required DLL files to system32 prompts me to confirm administrator privileges are needed to move these files, So I give the permission, copy the files to system32, and run wget to confirm. This is where it tells me it cannot find the DLL's required to run and when using regsvr32 it says it cannot find the entry point so it will not load the DLL asking me if it is a valid DLL or OCX file.

If I leave the DLL's that came with wget in the same folder as wget outsite of system32 they work vice adding them to system32 with the exe it will not work saying it cannot read the those dll files.

Is there a way around this or Do I need to Upgrade to Windows 7 to get away from these problems/restrictions?
