InstallAware

I've got a very basic install for a .NET 2.0 app (2 dlls, 1 exe) that, during an upgrade installation, won't overwrite the pre-existing files. This is using IA version 6.4 (build santacruz_sp2.031207)

My testing went something like this:
- Confirmed that all Install Files commands in the script have the Never Overwrite option unchecked
- Confirmed all Install File commands are before the Apply Install command
- Added multiple MessageBox commands to display variable values

Ran VS 2005 code build #329 (i.e. version 1.0.0.0329)
- Confirmed all 3 code files had correct date/time stamp and version number

Created IA install (web executable) for build 329
- Ran IA install for 329 on XP SP2 virtual machine
- Confirmed that all 3 files were installed and had correct version number

Ran VS 2005 code build for #330 (1.0.0.0330)
- Confirmed all 3 code files had correct date/time stamp and version number

Created IA install for 330
- Created new Revision Code in IA Project Options
- Compiled IA project into web executable
- Ran IA exe on same virtual machine
- Got message box confirming NEEDSUPGRADE = True
- Got message box confirming same TARGETDIR as 329 install
- Got message box confirming entry into [OFFLINE CONTENT] media block (only block in project)
- IA install completes successfully

However, when I go and look at the files in TARGETDIR, they all show the old version (build 329) and date/time stamp.

If I run the 330 install on a clean VM, the file versions are correct. Only during an upgrade do the Install File commands not work as expected.

This has me stumped. Any ideas?

Try logging, to see why MSI is skipping the file?

My install script is based on the IA samples with multiple modifications. One change I made was to remove the code in the prerequisites section that uninstalls the previous version. During testing I added this code back into the IA script, and now the install behaves as expected during upgrades.

Is the "Install/Remove MSI package" command to remove the previous version a requirement for upgrades?

Yes. That is a hard-requirement. If you do not wish to uninstall the older versions, you should then build your latest setup as a patch instead.
