== About ==
Short and simple macro to extend LogicLib to allow for testing the system for MSI packages that are installed with the same UpgradeCode as provided.

== Example ==
<highlight-nsis> ## This example uses the MsiEnumRelatedProducts MSI API call to determine
## if an msi package on the same upgrade track as the provided GUID is
## installed.
${If} ${RelativeInstalled} `{D8968392-698B-4A41-B6AD-C25C6608A69B}`
DetailPrint "A package is installed on the same track."
${Else}
DetailPrint "No software track is installed matching the the supplied GUID."
${EndIf}</highlight-nsis>

== Macro ==
<highlight-nsis>!include "LogicLib.nsh"
!define RelativeInstalled `"" RelativeInstalled`
!macro _RelativeInstalled _a _b _t _f
!insertmacro _LOGICLIB_TEMP
System::Call `Msi::MsiEnumRelatedProducts(&t39 '${_b}',i 0,i 0,&t39 n)i .s`
Pop $_LOGICLIB_TEMP
!insertmacro _== $_LOGICLIB_TEMP 0 `${_t}` `${_f}`
!macroend</highlight-nsis>

== Issues ==
* Only tested on XP x86
* Requires Microsoft Installer to be previously installed. If it isn't then it's likely that no MSI packages are installed anyway ;-)
