There was a problem with WAMP5 (on 5th October 2006) on Windows 2000 since it uses the word "reg" (not regedit) to make changes to the registry.
Windows 2000 users need to download Support Tools for Windows 2000 SP4, which can be downloaded from

www.microsoft.com]
To make the apache install_services.bat batch file a and the relevent line in the menu .ini (both containing "reg"
operate.
I installed the support tools and the "file not found" error message went away.
I still have not succeed in getting apache to start up yet though.
