When you install Phpnow, you experience the following issues:
installation Service [APACHE_PN] failed. Possible causes are as follows:
1. The service name already exists, please uninstall or use a different service name.
2. Non-administrator privileges, cannot operate Windows NT services.
Please confirm the operating system version first. If you are using Windows Vista or Windows 7, you should first exclude permissions issues. You can enter "cmd" in "Start-search", find "cmd.exe" in the search results, right click, and select "Run as Administrator". Then use the DOS command to rerun "Phpnow" to extract "Init.cmd" from the directory:
C:\>CD Phpnow
C:\phpnow>init
If the installation fails using the above method, you can try to start command prompt (CMD) again as described above, and go to the "Pncmds" directory of Phpnow, where "absolute forced uninstallation. CMD" is performed:
C:\>CD Phpnow\pncmds
C:\phpnow\pncmds> Absolute Forced uninstallation
Then delete the Phpnow directory, restart the computer, and then perform a "setup.cmd" reinstall.
The above describes the Phpnow installation Services [APACHE_PN] failure to solve the problem, including aspects of the content, I hope to be interested in PHP tutorial friends helpful.
