Scenario: SomeMSI.msi with version 2.0.1.0 has already been installed on local
computer.
Purpose: When a user runs SomeMSI.msi with version 2.0.2.0, the bits of 2.0.1.0
should be upgraded to 2.0.2.0
Problems: When the newer version of the msi is launched by "msiexec /I
SomeMSI.msi REINSTALL=ALL REINSTALLMODE=vomus", an error occurred complaining
that the SomeMSI.msi with version 2.0.1.0 cannot be found.
The .wxs file is looked like:
<Wix xmlns='http://schemas.microsoft.com/wix/2003/01/wi'>

......
</InstallExecuteSequence>
<CustomAction Id='AlreadyNewestSE' Error='Spec Explorer 2 has already been
updated.'/>
......
</Product>
</Wix>
Note that the environment variables _BLDVERMAJOR, _BLDVERMINOR, and
_BLDNUMMAJOR are used to automatically update the version fields when building
the msi.
Anyone can give me some suggestions?
Thanks,
Xin
