.NET Install Package Sometimes does not completely remove previous versions

Question

I am distributing my application using the VS2008 installation package, which usually works fine. When I create new versions of the application, I enable and extend the property Versionin the installation package and verify that the property is RemovePreviousVersionsset to True.

This works very well in most cases - I just run the installation package for a newer version, and the old version is deleted, and the newer version replaces it.

However, sometimes the installation package starts successfully, but when I run the program, the old version starts. Apparently, the old version of .exe is still present.

I need to completely remove the software and install a new version that always works, but it’s a pain.

The file is not used, as far as I can tell, and the installation package does not tell me to reboot.

Any ideas on what's going on here?

Answer 1

Not a direct answer, but the key difference between updating and uninstalling + reinstalling is that any custom uninstallation steps are not called in 2k8, but in 2k5.

This is stated in Visual Studio 2005 → Question about updating the installer project 2008/10

Another difference associated with this is that in 2k8 files are updated based on the version information resource - if your modules do not have newer versions, they are not replaced.

In some cases, you have a strong name, but I'm sure the last paragraph covers the problem you are seeing.
