Fix/Workaround Sorry we do not provide fixes or workarounds for a damaged registry! If you cannot find a tool that will fix your registry I am afraid you may be looking at a full reinstall of windows.
One thing you could try is installing wamp on another PC ( on the same drive you want to install it on this PC ) i.e. to C:\wamp if that where you want it.
You could then copy the C:\wamp folder from one PC to another.
Run \wamp\wampmanager.exe
On the wampmanager icon in the system tray do
wampmanager -> MySQL -> Service -> Install Service
wampmanager -> Apache -> Service -> Install Service
wampmanager -> Start All Services
I have not actually tried it, but it should work.
