Hi!

I am a newbee...

We made a major release for our product.
The sequence is as below:
-Changed the product code, product version
-changed package code
-added an entry in the upgrade table in the direct editor.
-added securecustomproperties.

This package when installed creates 2 shortcuts in add/remove programs.


Thanks in advance!

Do you have the FindRelatedProducts and RemoveExistingProducts standard actions in your InstallExecute sequence?
Generate a verbose log to see what's going on.
Make sure the ALLUSERS proeprty has the same value for the old and the new version.

There is a note in MSDN:
QUOTE
Windows Installer uses only the first three fields of the product version. If you include a fourth field in your product version, the installer ignores the fourth field.
