Products

Issue/Introduction

The silent install may not work with 11.4 or 11.4 SP1 with the properties copied from DVD ISO.
Silent install command:

setup.exe -f win_install.properties

 

Environment

CA WA Agent 11.4 
OS Windows

Cause

The silent installer uses the installer properties file.  If the properties file has unrecognizable characters then setup will not be able to read the file.
 

Resolution

In Windows, open the file with Notepad or Notepad++.  Delete all the lines with comments that start #.
There may be a special hidden character at the start of file. 

INSTALLER_UI=SILENT
ACCEPT_EULA=ACCEPT

Note: The special characters (see above) are not visible in Windows Notepad.  Open the file Word with MS-DOS encoding, the special character will be visible.  Remove the character and save it.

In Linux/UNIX use vi to open the properties file and special characters can be seen.  Delete or remove them and save the file again.
