I have similar problem ( same Win-7 64 Bit ) WAMP was installed. When executing nothing shows on the screen ..but it shows in task manager { WAMPMANAGER.exe *32 } as running.
In Hosts file There are several lines with 127.0.01 as follows:
# localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost 127.0.0.1 activate.adobe.com 127.0.0.1 practivate.adobe.com 127.0.0.1 lmlicenses.wip4.adobe.com 127.0.0.1 lm.licenses.adobe.com
