We are pleased to announce the release of Windows Installer v3.0 (MSI3.0) RC1. This release contains improvements to simplify application servicing. The redist package will not install on WinXP-SP2/RC1 or Win2k03/SP1.
New features in the MSI3.0 / RC1 release:
Authors need to explicitly mark patches in order to support uninstall.
The new MsiPatchMetadata table provides additional information about a patch - including whether it supports uninstall
PatchWiz.dll, the SDK tool used to create MSPs has been enhanced to support the new MsiPatchSequence and MsiPatchMetadata tables. It can also generate automatic patch sequencing information that should suffice for simple product servicing. PatchWiz has been optimized to significantly reduce the time taken to create patches.
MSI30 and update.exe support the same standard command line options to make it easy for administrators to control display, reboot behavior, install, uninstall, log generation and applying updates. Try msiexec /? after you install the RC1 bits.
Thank you for participating in this beta program. We look forward to your valuable feedback.
