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
