Error 1722

Windows UAC (User Account Control) can cause the client installation to fail with a message like the following:

You must have an administrative privilege to run this tool.

This happens even when being launched by an `Administrator'. The WPKG logs show this:

Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action _A9459942_EE79_497A_9080_F39DDA8A7B80, location: C:\Program Files\wpkg\wpkginst.exe, command: --SETTINGSFILE=

The solution is to launch a command window with elevated privileges and use that to start the installer. Quoting from one post of many:

Install

1. Make shortcut to cmd.exe
2. Right click on it and select runas administrator
3. "cd" to path where installer is, e.g. cd C:\Users\Myname\Downloads
4. Run your msiexec command.
   1. msiexec /i "WPKG Client 1.3.14-x32.msi"
   2. For network, enter full path i.e msiexec /i "\\server1\MyShare\WPKG Client 1.3.14-x32.msi"

Install Alt

1. For install across network or localy use "psexec" from Systeminternals with localhost and "-h" parameters, eg. "psexec -h localhost msiexec /le wpkg_error.txt /i WPKG_Client_1.3.14-x64.msi"
