Hello I have Windows VIsta Home Premium, and the solution was so easy for me.
- just go to the WAMP instaler (.exe) and make right click and click in PROPERTIES
- go to COMPATIBILITY and in Compatibility mode CHECK Run this program in compatibility mode for:
WINDOWS SERVER 2003 (SP1)
- click in OK
and that's all EASYYYYY!!!! i try a lot of times before do this and firefox show me a blank screen, but after this WORKS PERFECTLY!!!!
If you have the software installed and it doesn't work, uninstall it and use some software for clean the registry (i used Vista manager) restart and try to install again with Winserver compatibility.
I hope that this easy solution works for you to.
PEACE!!!
