Zend Server Installation Error:-1622 Error opening Installation log file


Applies To: 

[ Zend Server ]
[ Windows ]


When installing or removing Zend Server on Windows, the installation process might fail with the following error message:

Error:-1622 Error opening Installation log file. Verify that the specified log file location exists and that you can write to it.

Technical Details

The above error reflects a lack of write permissions on the log folder for the current user.


You can provide an alternative folder for the installation log by adding extra command line parameters.

1. Open the cmd console as admin user:

    a) Type "cmd" in the start menu quick lookup.

    b) Right-click cmd.exe and select "Run as Administrator" from the context menu.

    c) Alternatively, you can locate the cmd console under Start -> Programs -> Accessories, then right-click "Command Prompt" and select "Run as Administrator" from the context menu.

2. From within the cmd console, cd (Change Dir) to the Drive / Folder which contains the Zend Server installer.

3. From within the cmd console, execute the installer with extra parameters to create the log file in an alternative folder:

    a) Using System Temp folder: ZEND_SERVER_SETUP.exe /v"/L*v\"%temp%\zsinst.log\"

    b) Using C: folder: ZEND_SERVER_SETUP.exe /v"/L*v\"C:\zsinst.log\"

4. After the installation / uninstallation is complete, you can safely close the cmd console.
