I have installed XAMPP (xampp-win32-1.8.2-0-VC9-installer.exe) on Windows 7 successfully. But unfortunately, the following error was found during running Apache from XAMPP C
Had the same problem and none of the above solutions worked. So, by reading carefully the logs, I found this message :
10:55:42 [Apache] Port 443 in use by ""C:\Program Files (x86)\VMware\VMware Workstation\vmware-hostd.exe" -u "C:\ProgramData\VMware\hostd\config.xml"" with PID 1908!
In my case, I had just to stop the VMWare service which was running automatically.
The key is to read carefully the message given by XAMPP Panel when started.
Hope this help!
