The following package identifies the client form factor and writes an entry into the Registry which can subsequently be read by other application install packages.

It relies on a vbs script which queries WMI to identify the hardware chassis type then writes the returned value to wherever you specify in the Registry.
I have added it to the Registry section which specifies Env Variables so you have the choice to query the variable "CHASSISTYPE" or directly query the registry key in a WPKG check condition.

You can use logical conditions to determine if an application install package targets a specific platform (laptop or desktop for example). Remember that logical conditions are counter-intuitive, if you want to install an application on a specific platform you check for what your target platform isn't.

For example:

	<check	type="logical" condition="or">
		<check type="uninstall" condition="exists" path="SonicWALL SSL-VPN NetExtender" />
		<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Desktop"/>
		<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Other"/>
		<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Unknown"/>
	</check>


Alternatively you can use an if statement in your install command to only install if the appropriate chassis type is detected, e.g. 

<install cmd='%COMSPEC% /c if "%CHASSISTYPE%"=="Laptop" msiexec /qn /i ...

Of course be sure to modify the xml and vbs below to your needs.

Check Chassis Type

<?xml version="1.0" encoding="UTF-8"?>

<packages>
  <package
    id='chassistype'
    name='ChassisType'
    revision='1'
    priority='999'
    execute='once'
    reboot='false'>
 
	<check	type="logical" condition="or">
	<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Desktop"/>
	<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Other"/>
	<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Unknown"/>
	<check type="registry" condition="equals" path="HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\CHASSISTYPE" value="Laptop"/

	</check>
 
    <install cmd='cscript //B "%SOFTWARE%\system\identify_chassis_simple.vbs"' />
		 
    <upgrade cmd='cscript //B "%SOFTWARE%\system\identify_chassis_simple.vbs"' />
 
    <remove cmd='REG DELETE "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\" /v CHASSISTYPE /f' />

 
  </package>
</packages>


Now I have two different versions of the vbs script, the identify_chassis_simple.vbs script writes "desktop" or "laptop" for a number of different chassis type return codes. The identify_chassis.vbs script at the bottom has a lot more chassis types if you need that granularity in your application installs (I don't).
