Installshield does not consider revision number in warning

Lets say my current production version is 1.2.3 and the new product version is 1.2.3.4.

Now, during installation, it will throw a warning message saying something like "The setup has detected the version 1.02.003 of...... already installed. This setup updates ..... to the same version that is already installed, therefore this update is not needed. Do you want to install the update anyway? "

This will be very misleading. Does anybody know a solution for this?

It is not InstallShield, but rather Windows Installer, the underlying technology has the behavior you observe. Take a look at this article, which explains how Windows Installer treats versioning.

The important part for your case is this:

Note that 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.

This explains why it considers the new one to be the same version. So, the suggestion is either change the third digit, or go with small updates instead. Here is how you can apply small updates by re-installing the product.
