Windows Installer 3.1 Redistributable
Overview
The Microsoft® Windows® Installer is an application installation and configuration service. WindowsInstaller-KB893803-x86.exe is the redistributable package for installing or upgrading Windows Installer.
Issues that are addressed in Windows Installer 3.1
• Windows Installer now logs null characters ("[~]") correctly when the characters are used in a registry value marker or in a service dependency.
• The MsiGetFileHash function now works correctly for very large unversioned files. These files may be about 2 GB.
• The MediaSrcProp property of a patch is now set to the original launched-from location when the patch is installed. The MediaSrcProp property is set to the cached patch location for subsequent transactions.
• The progress bar now works correctly even if the package contains a file that is larger than 2 GB.
• Patching of isolated components now works.
• Target information for a custom action is no longer logged when the custom action fails if the custom action is marked to hide the target.
• Error 1642 (ERROR_PATCH_TARGET_NOT_FOUND) is returned even if only one Windows Installer 2.0-style inapplicable patch is being applied.
• Applying a full-file Windows Installer 2.0-style patch that contains companion files no longer requires access to the source media.
• Windows Installer 3.1 performance has been enhanced during initialization of a package that contains many features.
• Windows Installer 3.1 now correctly handles the scenario where a minor update package exists and an obsolete or superseded patch also exists.
• Patch application now handles cases where the Sequence column of the Patch table is larger than 32,767.
• Windows Installer 3.1 now sends INSTALLSTART_ACTIONSTART messages for all actions.
• In Windows Installer 3.0 and earlier versions, if you applied several major upgrade patches, subsequent installations occasionally failed. This issue is now fixed.
• Windows Installer no longer incorrectly initiates a repair operation when a component contains a 32-bit assembly on a 64-bit computer.
• The patch sequencer no longer incorrectly rejects a valid patch during administrative image patching.
• Windows Installer 3.1 no longer skips script custom actions that are marked as asynchronous.
