1.In VS 2003 create library project with Installer derived class. Then create Setup Project with custom action to run installer class. UninstallPreviousVersion=true
2. Install the setup on client machine.
3. Convert projects to VS2005 and build new setup.
4. Try to install it on the machine where previous version was installed.

Error 1001. Exception occurred while initializing the installation:
System.BadImageFormatException: The format of the file 'XXXXX.dll' is invalid.

Ideally setup should be able to uninstall previous version in background without any problems.
As a short term solution VS2005 conversion wizard should change UpgradeCode and document warning about it.
