My Hard disc just crash and i bought a used one, 500GB. Apache was working well on the crashed hard drive. I installed windowsXP SP2 OEM on the new hard disk. I downloaded WAMP x64 from the internet. After installation it gives me this error C:\wamp\bin\mysqld.exe is not a valid win32 application. When I press ok i also get another error C:\wamp\bin\apache\apache2.2.17\bin\mysql.exe is not a vaid win32 application. When i finish the installation and try to run the programme, i will also get the following error Aestan Tray Menu has encountered a problem and needs to close. We are sorry for the inconvenience. The server will not start. Pse am stranded. How do i move ahead from here. I need your help.
