Installation instructions - advanced
If you don't need such customized or advanced installation instructions, you can use an easy to use WPKG Client.
 Starting WPKG using Windows Task Scheduler
- create a small batch script called wpkg-start.bat and put it on your server:
cscript \\server\wpkg\wpkg.js /synchronize /quiet /nonotify
- open Scheduled Tasks from Start Menu -> Accessories -> System Tools
- double-click "Add Scheduled Task" and choose "Next"
- click on Browse and locate the wpkg-start.bat file you just created
- choose "When my computer starts" and click Next
- type-in the Username and password (this user needs to have administrative rights)
- choose Next -> Finish
This will create a scheduled job file, which you can copy to all other machines on the network (but you will have to renew credentials, as they are not stored in this file).
Alternatively, you may add a scheduled task from a command line (or during an Unattended install):
schtasks /create /tn wpkg /tr "\\server\wpkg\wpkg-start.bat" /sc onstart /ru domain\administrator /rp password
schtasks utility will work from the command line only in Windows XP or higher. If you have Windows 2000, and would like to install WPKG "silently", please see this page: http://www.windowsitpro.com/Article/ArticleID/25186/25186.html?Ad=1
Note that system commands in Windows are *incompatible* in different language versions of Windows! I'm not joking now!
For example, in German version of Windows, this command would look like that (note the
schtasks /create /tn wpkg /tr "\\server\wpkg\wpkg-start.bat" /sc beimstart /ru domain\administrator /rp password
If you're not sure, consult schtasks help:
 Starting WPKG using Samba, winexe and preexec/postexec directive in smb.conf
 Starting WPKG using Active Directory client
Basically, you don't have to configure anything on the client, because everything was configured on the Active Directory server (see above - Server side).
One thing you might need, is cscript binary - it is not shipped with Windows 2000, so you may have to add it to your clients (see above).
See also WPKG with Active Directory for a description with screenshots.
 Starting wpkg using cygrunsrv.exe
An easy way to start WPKG as a service is to use cygrunsrv.exe from Cygwin.
You don't need to install Cygwin, it's enough if you copy cygrunsrv.exe binary and cygwin1.dll library.
Download: cygrunsrv.exe and cygwin1.dll
With cygrunsrv, it's easy to start WPKG as any user you want (SYSTEM, local administrator, domain administrator, (Limited/Restricted?), etc.)
For cygrunsrv usage, see
You can get cygwin1.dll from any Cygwin mirror, it's a compressed file located in the cygwin/release/cygwin directory (for example, cygwin-1.5.19-4.tar.bz2).
Cygrunsrv is similarly located in cygwin/release/cygrunsrv (for example, cygrunsrv-1.16-1.tar.bz2).
Here's one working example:
cygrunsrv -I wpkg -p '/cygdrive/c/WINDOWS/system32/cscript.exe' -a'c:\wpkg\wpkg\wpkg.js /quiet /synchronize' -c '/home/Administrator/wpkg/wpkg' cygrunsrv -S wpkg
Those arguments are:
- -I [name]
- Install a service named [name]. In this example, we're calling it wpkg.
- -p [/path/to/executable]
- Path to the command to run -- in this case, cscript.
- -a [arguments to executable]
- Arguments for the executable -- in this case, the path to wpkg.js and how we want it to run.
- -c [directory]
- Go to this directory before starting the program.
- -S [name]
- Start the service.
There are a few things to note:
-pargument gives the path to cscript in the format Cygwin uses to get to Windows drives. In this format, the C: drive can be reached at
/cygdrive/c, the D: drive can be reached at
/cygdrive/d, and so on. Also, unlike Windows, Cygwin is case-sensitive -- so
/cygdrive/c/Windowsis not the same as
-aargument is given in Windows format. Also, it is very specific to the (stupid) way I have wpkg set up on this machine.
- I'm unsure if the
-cargument is necessary, but it works for me. It's given in Cygwin/Unix format, and is again very specific to the stupid way I have things set up. I'm unsure what to put here if all you're doing is copying around the Cygwin DLL.
- Cygwin saves the STDERR output to
/var/log/wpkg.log(assuming you named the service wpkg). Again, I'm not sure where this would go if you're just copying around the Cygwin DLL.
 Starting WPKG using srvany to create a system service (advanced)
All you have to do is to login to your Windows box, and issue these commands as Administrator - you can put them in one file which we call
Here is a sample
wpkg-install.bat file - the sum of steps 1-8 described below. You may want to change some paths of course.
SET SRVPATH=\\server\wpkg\files copy %SRVPATH%\srvany.exe %SystemRoot%\System32 copy %SRVPATH%\instsrv.exe %SystemRoot%\System32 instsrv "Windows Packager" "%SystemRoot%\System32\srvany.exe" %SRVPATH%\scripten.exe /Q /R:N cscript.exe %SRVPATH%\install-service.js net start "Windows Packager"
We are using the
instsrv.exe programs included with the Windows 2000 Resource Kit to install the wpkg.js script with the
/synchronize /quiet options as a system service.
instsrv.exe programs cannot be distributed along with this software for licensing reasons. However, you can find links in the download section.
It is quite easy to implement this yourself (for the impatient, all commands shown are able to be copy and pasted, or they're available as downloads below):
instsrv.exefiles and put them on your file server.
- Pick a network drive. This drive must be accessable by the user WPKG is going to be configured to run as. We are using LocalSystem on Windows 2000. Windows XP has a new NetworkService account which begs examination. When LocalSystem attempts to access a file share, it does so under the identity of guest. Thus, guest must have read only access to your entire software share.
- Our first command copies
copy \\server\wpkg\files\srvany.exe %SystemRoot%\System32 copy \\server\wpkg\files\instsrv.exe %SystemRoot%\System32
- Then we run:
instsrv "Windows Packager" "%SystemRoot%\System32\srvany.exe"
This creates the Windows service called "Windows Packager". It is however not yet started.
- Next, we install the latest version of Windows Script Host on the system. Windows 2000 by default does not have an up-to-date enough version. Check Microsoft's web site for the Windows script software. The executable is named
scripten.exe("Windows Script 5.6 for Windows 2000 and XP") . We launch it from the
wpkg-install.batfile as follows:
\\server\wpkg\files\scripten.exe /Q /R:N
This makes it install quietly and not reboot.
- Next in our
wpkg-install.batfile, setup the registry entries necessary for
srvany.exeto properly start Windows Packager. It can be done by calling a JScript file:
install-service.js. This is done because the registry keys needed have the potential to be different for each system. The
install-service.jsfile sets the following keys:
HKLM\System\CurrentControlSet\Services\Windows Packager\Parameters\Application HKLM\System\CurrentControlSet\Services\Windows Packager\Parameters\AppParameters
The Application key specifies the full path to the executable that the service will run at boot. This is because we do not launch the wpkg.js file, we launch the Windows Scripting Host (
cscript.exe) and instruct it to launch the wpkg.js file. Set the Parameters key to:
\\server\wpkg\wpkg.js /synchronize /quiet /nonotify
cscript.exe to run the wpkg.js script, which is placed on the network share, with the two options shown. It will synchronize the system on boot, logging errors quietly.
- The last entry in the wpkg-install.bat file starts "Windows Packager" service:
net start "Windows Packager"
To sum up, we have two files needed to install WPKG on a given Windows machine:
wpkg-install.bat, which copies all needed files, and
install-service.js (started within
wpkg-install.bat), which installs WPKG as a service in Windows registry - so that it could be launched each time the machine is booted.
wpkg-install.bat needs to be run only once.
This is an example
var WshShell = WScript.CreateObject("WScript.Shell"); var srvKey = "HKLM\\SYSTEM\\CurrentControlSet\\Services\\Windows Packager\\Parameters\\"; var appKey = srvKey + "Application"; var parKey = srvKey + "AppParameters"; var srvPath = WshShell.ExpandEnvironmentStrings("%SystemRoot%") + "\\System32\\cscript.exe" var srvArgs = "\\\\server\\wpkg\\wpkg.js /synchronize /quiet"; WshShell.RegWrite(appKey, srvPath, "REG_SZ"); WshShell.RegWrite(parKey, srvArgs, "REG_SZ");
wpkg-install.bat file on a new system will now set up and run WPKG! Running this
wpkg-install.bat file as part of your Windows install answer file is ideal.
Watch Windows reboot. Imagine you have over 20 packages being installed, half of which require a reboot. It's amusing to see Windows reboot itself for 30 minutes installing stuff.
