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.
You will then need to use logical conditions to determine if an application target at a specific platform (laptop or desktop for example) is installed. 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:
<!-- The registry checks below mean this package will only run on a laptop as defined by chassistype package
Remember that if any of the check conditions returns true the package is _not_ installed -->
<check type="logical" condition="or">
<check type="uninstall" condition="versionequalorgreater" path="SonicWALL SSL-VPN NetExtender" value="3.5.108" />
<check type='registry' condition='exists' path="HKLM\Software\xxxxx\wpkg\ChassisType" value="Desktop" />
<check type='registry' condition='exists' path="HKLM\Software\xxxxx\wpkg\ChassisType" value="Other" />
<check type='registry' condition='exists' path="HKLM\Software\xxxxx\wpkg\ChassisType" value="Unknown" />
</check>
Of course be sure to modify the xml and vbs below to your needs.
<?xml version="1.0" encoding="UTF-8"?>
<packages>
<package
id='chassistype'
name='ChassisType'
revision='1'
priority='999'
execute='once'
reboot='false'>
<check type='registry' condition='exists' path="HKLM\Software\xxxxx\wpkg\ChassisType" />
<install cmd='%COMSPEC% /c cscript //B "%SOFTWARE%\system\identify_chassis_simple.vbs"' />
<upgrade cmd='%COMSPEC% /c cscript //B "%SOFTWARE%\system\identify_chassis_simple.vbs"' />
<remove cmd='REG DELETE HKLM\Software\xxxxx\wpkg\ /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).
The most important fields to modify in the vbs below are strKeyPath and possibly strValueName to suite your environment and ensure it is the same as the checktype registry path.
