+.SYNOPSIS
+    This script is intended to recache the MSI sources, if deemed missing, for Adobe Acrobat x86 installations. Optionally, if repair is not possible, it can run AdobeAcroCleaner_DC2015.exe to allow for a clean reinstallation.
+.DESCRIPTION
+    Sometimes, updates for Adobe Acrobat x86 fail due to MSI missing sources. The issue is so widely known, even by Adobe themselves, it's why they made AdobeAcroCleaner_DC2015.exe.
+
+    This script will attempt to repair the MSI sources for Adobe Acrobat x86. If the repair is not possible, it can optionally remove the installation to allow for a clean reinstallation by using the -RemoveIfRepairFails switch.
+
+    AdobeAcroCleaner_DC2015.exe is expected to be in the same directory as this script when using the -RemoveIfRepairFails switch. If not found, the removal step will be skipped.
+
+    The script determines if the MSI source sources are missing by using the following logic:
+        1. Check if the LocalPackage registry value exists and points to a valid file.
+            HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\{CompressedGUID}\InstallProperties\LocalPackage
+        2. If not, check each network path listed in the Net registry key for the presence of the MSI PackageName.
+            HKLM:\SOFTWARE\Classes\Installer\Products\{CompressedGUID}\SourceList\Net
+    If neither are found, the script assumes the MSI sources are missing and attempts a repair.
+.PARAMETER RemoveIfRepairFails
+    If specified, the script will invoke AdobeAcroCleaner_DC2015.exe to remove the Adobe Acrobat installation if the repair attempt fails.
+.EXAMPLE
+    .\Repair-AdobeAcrobatRdrx86.ps1 -RemoveIfRepairFails
+    Attempts to repair the Adobe Acrobat x86 installation. If the repair fails, it will remove the installation.
