Apache Friends Support Forum

Hi
Novice here, trying to install xampp 3.2.1.0 on Windows 10 Home 64-bit. Am using it for a MySQL class so downloaded the version recommended by the instructor xampp-win32-1.8.3-3-VC11-installer.exe from his website which has apparently worked successfully for lots of folks.
First, I had firewall issues, then http.sys issues -- corrected those with the advice from these boards.
Apache then started fine BUT as soon as I exited and tried to restart, no luck.
So I uninstalled, rebooted, etc etc.

The latest error log:

[Sun Apr 28 15:01:11.458215 2019] [mpm_winnt:notice] [pid 6600:tid 740] AH00455: Apache/2.4.7 (Win32) OpenSSL/1.0.1e PHP/5.5.9 configured -- resuming normal operations

MySQL starts fine, but not Apache. Haven't been able to locate anything yet that applies to this exact problem.
Do I somehow still have a port conflict?
Any help would really be appreciated.

Additional info: When I try to start Apache, the control panel shows PID as 15800. Then after a bit, it shows ports as 80, 443.
Then a quick flash on screen of another PID, not there long enough to be sure what it says but looks like 15400 or 15840. At that point, Apache errors out.

Hi again - OK, completely uninstalled the version the instructor suggested (win32-1.8.3-3-VC11 etc) and took the download from ApacheFriends website xampp-windows-x64-7.3.4-0-VC15.installer.exe.

Control Panel V3.2.3
Get essentially the same error (different child process number):

Help please - I know very little about pc setup, or even basic DOS commands. If someone could just point me in a general direction.... I've scoured this board and can't find anything that works.
Thanks
