1.  Look in your verbose log file.  It will explain why the original MSI was 
required.

2.  Does helper.dll have a newer file version?

Subject: [WiX-users] Running minor upgrade sample codes

I am running the sample codes that came with the wix tutorial (version 2.0) for 
minor upgrade.

First of all, I created the initial install package which I named it as 
"sampleOld.msi".  The install process ran without any errors.

After that, I created the second install package which I named it as 
"sampleNew.msi".  I follow the instruction to open a command prompt and ran the 
instruction as follows:
"msiexec /i samplenew.msi REINSTALL=ALL REINSTALLMODE=vomus"

I can see two problems when running this command.
1. If the original install package does not reside on the same directory, it 
gave the following error:
"A network error occurred while attempting to read from the file: C:\temp\Wix 
tutorial\lesson4\SampleUpgrade\New\sampleOld.msi"
I have to copy the old file ("sampleOld.msi") from other directory to the 
current directory.  I don't think this is neccessary and it is an error.

2. I intentionally "touched" the helper.dll file so that its timestamp is newer 
than the old one.  After the upgrade ("sampleNew.msi") is finished, I don't see 
the new file was copied.

Anyone has the experiement and how to solve the problems?

Thanks in advance for assistance.

Michael
