遇到这两个错误后不管它，继续安装。完成后下载Microsoft Visual C++ 2008 Redistributable Package (x86)，可以到这里下载：Microsoft Visual C++ 2008 Redistributable Package (x86)，安装完这个之后双击xampp安装目录下的setup_xampp.bat文件，最后运行安装目录下的xampp-control.exe文件，此时启动Apache就可以成功了。——知乎仰望星空
Important! Because an activated User Account Control (UAC) on your sytem some functions of XAMPP are possibly restricted. With UAC please avoid to install XAMPP to C:\Program Files (x86) (missing write permisssions). Or deactivate UAC with msconfig after this setup.
安装目录最好选择C盘之外的其它磁盘，如果选择C盘安装，由于用户权限原因，会出现创建一些文件失败的问题。如果你已经据有最高权限，可以直接装在C盘。
一般刚安装完xampp时，apache服务器是启动不了的。

网上找了解决办法
2.httpd-ssl.conf
我试过了还是没有解决
后来发现在xampp根目录下有两个个文件properties.ini和xampp-control.ini
1、打开properties.ini，找到
[General]
installdir=D:\xampp
base_stack_name=XAMPP
base_stack_version=1.8.3-1
base_stack_platform=windows
require_root_privileges=1
[Apache]
apache_server_port=80
apache_server_ssl_port=443
apache_root_directory=/xampp/apache
apache_htdocs_directory=D:\xampp/htdocs
apache_domainname=127.0.0.1
apache_configuration_directory=D:\xampp/apache/conf
apache_unique_service_name=
[MySQL]
mysql_port=3306
mysql_host=localhost
mysql_root_directory=D:\xampp\mysql
mysql_binary_directory=D:\xampp\mysql\bin
mysql_data_directory=D:\xampp\mysql\data
mysql_arguments=-u root -P3306
mysql_unique_service_name=
[PHP]
php_binary_directory=D:\xampp\php
php_configuration_directory=D:\xampp\php
红色标注部分设置了其实端口，依次修改成
apache_server_port=8088
apache_server_ssl_port=4431
1、打开xampp-control.ini，找到
[ServicePorts]
Apache=80
ApacheSSL=443
MySQL=3306
FileZilla=21
FileZillaAdmin=14147
Mercury1=25
Mercury2=79
Mercury3=105
Mercury4=106
Mercury5=110
Mercury6=143
Mercury7=2224
TomcatHTTP=8080
TomcatAJP=8009
Tomcat=8005
修改成
Apache=8088
ApacheSSL=4431
修改它。。。。
修改成8088,4431
