For the past several days, I used all my email accounts to register but all of them were trouble,
as your mail function might be out of order.
I finally successful today and tell me the answer, P L E A S E !
1. INSTALLATION PATH.
The default path is xampp and when I tried to do on my own like D:/
it was impossible, and I installed as D:/xampp/xampp...
Later, I changed to D:/xampp/....
Accordingly, I had to change many scripts for deleting double xampps.
Then, I became confused about the paths.
2. SCRIPT calling install\start.html
Now I get this error message when I clicked "xampp_start.exe", or "setup_xampp.bat" : cannot find instal\start.html
Where is the script which calls install\start.html?
I am still angry until you inform the aboves.
