Hi everyone

I have created an upgrade msi file, but it does not recognise previous install.  I think I have done everything according to the upgrade eg in the help -- create Upgrade Table with Upgrade Code from previous msi, put in min and max versions, language, attributes 769 (have tried several different attributes), action property "OLDAPPFOUND"...no luck.

I also changed the package code and product codes.  Basically I followed the example in the SDK help.

If anyone can help, I will be eternally grateful, I just do not know what I am doing wrong!!

Have you try
1025 for Attributes
OLDPRODUCTS for ActionProperty
and don't forget to use the same upgrade code for both versions.
