Strange Message during Upgrade

[BoboEGR]

Hi all,

i have coded an standard MSI installation for an simple program. A new version arrived and i builded the setup new with an new revision code, the rest was unchanged.

During the setup execution, an error (sorry i have it only in german) occured:

"Es wurde eine ältere Datenbank geöffnet und konvertiert.
Bitte die folgenden Hinweise und Warnungen beachten:
etc."

Whats wrong with my setup?

IA Version is 2012 Admin Studio.

Dear User,

For I what see (I have tried to translate your error message ... I hope is correct) ... seems that the database for the existing installation doesn't match the upgrade you are running.

this happens during a patch?

Regards.
