Hi All,
I have created a setup.msi package with some binaries. I am again creating the setup.msi package with modified binaries and trying to upgrade the product, but i am not able to do so. It is throwing the Following error
Another Version of this product is alread installed.
Installtion of this version can not continue. To configure or remove the existing version of this product, use Add/Remove Program on the Control Panel.

Note I have changed the Product version in the Installshield so that Minor upgrade can take place. I have not changed the Product code (dont want Major Upgrade).
Can some one help here.

Also can someone tell me how to change the Package ID in the InstallShield IDE.
I am using InstallShield 2008.

Thanks in advance...

To run a minor upgrade, add the REINSTALL and REINSTALLMODE properties on the command line of the .msi. Or, package your .msi with the startup launcher, and setup.exe will automatically detect the previous version and start the .msi with the appropriate properties.

Or, you can set the properties in the Property Table of the .msi, but then you must create a system search to detect a new install and "unset" the properties, if you intend to use the installation package for both new installs and upgrades.

Hi Kathy,
Thanks for the reply...

Do you mean that i need to check the product code in the registry and verify if it is installed and if not installed unset the properties REINSTALLMODE and REINSTALL.

if so do i need to put this custom action code after <First Action> in the installshield IDE.

Hi All,
I am able to run the update from the command line by passing the option REINSTALLMODE=vomus and REINSTALL=ALL, but i want to set these properties in the IDE or in Custom Action so that whenever my installer run in upgrade mode it should be able to upgrade.

Please help me. This is important for me.

Thanks a lot for the help...

You can't do this inside the msi but InstallShield's setup.exe can do this for you. But that requires that the user launches the update via setup.exe and not by double clicking the .msi file.

This guest article from Bhuvana aims at providing the requirement for minor upgrade, the steps to create it and options to install the same. I reckon, this article will be of an help - "How do you Create a Minor Upgrade using InstallShield"
