Hello all,

I have a need where a package will determine if a previous version exists, and 
then allow the user the option to upgrade the previous version, or to install 
the new version side by side with the existing, so both are available.

My current thought was to use the Upgrade table to detect the version,  and 
then modify the ActionProperty and remove a detected product depending on the 
user input.   Also, I will need to deal with the path issues for files and 
registry (I have done side by side installs before).

Has anyone got any guidance on doing this (or not doing it at all)?


Regards

Michael
