MSI Deployment Problem in GPO Environment

Question

Hello Friends  In our client network  our product is being installed through Group policy object with MSI . Each time changes come  we hv to update version in MSI Setup Project (VS2005). when user install this msi in this environment (GPO) they face message  unable to install a product bcoz newer version already installed  even user try to update new version on existing old version . at our local development environment  we are not facing this problem. Also we have set 2 property DetectNewerVersion = true / false (message comes in both) RemovePreviousVersion = true what can be cause of this ? 1) GPO settings (bcoz we are not facing in testing) 2) MSI settings (upgrade code change before since last few versions -which we don't know how it changed) 3) Registry problem might occured at one of client PC ? Plz Plz help . Thanks in advance . Regards Yogesh

Hello  Thanks for reply. Our upgrade code was changed before few months which we don't know how it was changed. Is there any possibility that this Message newer version already comes due to this change ? As you suggest  Product code always change while version change . Also DetectNewerInstalledVersion & RemovePreviousVersions is same as you told . Plz help . Regards Yogesh

so it has to be one of the following but since it works in your local environment there is something else in the client machine which is unknown need to look deeper. 1. Increment the Version property. 2. Version property of installer project. 3. Change the ProductCode property. 4. Keep the value of UpgradeCode property it needs to stay the same. 5. RemovePreviousVersions to true 6. DetectNewerInstalledVersion to false.

Hello  Scenario is as below ================ We develop Application & in our 3-4 developer's pc no one face problem such like newer version already installed even if we install any new setup (like 5.51/5.52/..) on any old setup(5.49/5.50) But at our client 's location (which is in another country)  users are given this setup through GPO in their network . when end user try to install this MSI  they get message newer version... though no new setup installed !! & we can not replicate / check this issue at our local environment. & this issue comes since last few setup . -- Also in every MSI update  we change product version so Product code changes every time . So plz help in this kind of situation how to replicate/track issue ? Thanks in Advance Regards Yogesh

ok default value is true and you said that you changed it to false and still the same so it works on local machine but not on server...hmm.. did you check that you are using different Setup project version number and ProductCode?
