you could probably do it with a batch file assuming all you need to do is..
-create a folder with 2 sub folders
MD c:\mainfolder\subfolder1
MD c:\mainfolder\subfolder2
-add dlls to system 32
copy x:\mydlls\*.dll %windir%\system32\
-register dlls with system (if they need it)
regsrv32 %windir%\system32\firstone.dll
regsrv32 %windir%\system32\secondone.dll
Alternatively you need some free installer type thing. I had a quick google and found
CreateInstall: Freeware installer CreateInstall FREE and theres quite a few there.
