我尝试过的步骤包括：从数据目录中删除lblogfile0和lblogfile1文件，从mysql配置文件中删除innoDB目录路径。有没有人对这个问题有任何想法？

来自XAMPP Windows Help
Microsoft提供了一个更好的防火墙，其中包含自动启动的Service Pack 2（SP2）。此防火墙现在阻止必要的端口80（http）和443（https），Apache无法启动。
快速解决方案：
使用工具栏禁用Microsoft防火墙，并尝试更多地启动XAMPP onces。更好的解决方案是在安全中心内定义一个例外。
The following ports are used for basic functionality:
Apache (HTTP): Port 80
Apache (WebDAV): Port 81
Apache (HTTPS): Port 443
MySQL: Port 3306
FileZilla (FTP): Port 21
FileZilla (Admin): Port 14147
Mercury (SMTP): Port 25
Mercury (POP3): Port 110
Mercury (IMAP): Port 143
Mercury (HTTP): Port 2224
Mercury (Finger): Port 79
Mercury (PH): Port 105
Mercury (PopPass): Port 106
Tomcat (AJP/1.3): Port 8009
Tomcat (HTTP): Port 8080

从日志中可以看出，InnoDB引擎无法分配数据文件。最好的方法是卸载并重新安装。还要检查哪个版本与Windows XP兼容，因为最新的版本不是（需要1.8.2）。
