Hi,

if you wnat just know whether the application has been upgraded or not you can find out by doing below things

1. Double click the msi, in full UI while installing it will show a message that "Removing previous version" on the progress dialog window.

2. after installating the application, launch the shortcut got o help tab, and check the version it should have been upgraded.

3. can verify the version of the files.

i guess what u mean is...while installing, check whether the fix is applied, if applied, abort install and if not, apply fix..are we on the same boat?

IF thats the case, you can use System Search function, where u can look for a file version, size, or registry entry which tells u that the app is fix...if the app finds that it aborts the install with an optional Message Box informing user that the fix is applied or if it doesn find the latest fix, it will apply it... do a search here or on Google how to mingle with System Search.

Is there a MSI property which will give a true/false to if this installion is an upgrade?


I'm not understanding this part. You should know whether or not the installation is an upgrade...what information are you looking for?

Question is confusing
