Product Version

[Trax]

We have three products that we build into an MSI. They all have the same Company Name, similiar Product Versions (09.09.xxxx where only the xxxx is usually different but can also be the same), but different Product Names. They also have Automatically upgrade older product version selected in the Upgrades section. We are coming across an issue now where someone is trying to install two different products where one product, that is already installed, has version number 09.09.0721 and the second product, they're trying to install, has version number 09.09.0712. The Error states that a new version of the product already exist. Should this be happening? If so, Why?

Hi,

Most likely when you've created the projects you've copied the .aip file from the first one and modified it according to your requirements. This is not correct because then you also copied the GUIDs from the old project.

Because all the products are different they should have different GUIDs(Product Code, Upgrade Code, etc.).

Here is a solution :
- save the old project as a template, File → Save As Template
- on the New Project Dialog go to Custom Templates tab and select the project template you've saved previously.

The template project will have the same settings of the initial project except all the GUIDs are changed. This way, the resulted package will be seen as a completely different package compared to other packages created from the same template.

Thanks that is exactly what I did . Is there a way I can see the GUIDs to make sure they are different this time?

Hi,

Yes it is. To see the Product Code and Upgrade Code you can go to Project -> Options -> Project IDs tab. For the components GUIDs you must go to the Organization page, select each component from the tree and in the Component Properties page it will appear the GUID field corespondent to it.
