InstallAware

I have reposted this original problem in hopes that it will be easier for others to find the solution.

Problem:
Error dialog appears during an install with no additional description regarding the cause of the problem.

Scenario
I have two applications... lets call them App1 and App2:
>If I install App2 first and then install App1, everything works as planned.

>However, if I install App1 first and then install App2, I get an error message dialog appearing with the very descriptive word "Error" (and a 'Big Red X').

>This error msg appears almost immediately after the 'Progress' dialog screen appears.

> If I run the installation in debug mode I find that the error dialog appears in the MSI script precisely at the ‘Apply Install’ command.

Solution:
The workaround is to generate a new "Upgrades Product with Product Code" GUID for the installation project. After creating a new Upgrades Product with Product Code" GUID, the installations will work correctly.

Just follow these two simple steps:
1. Display the Project Options dialog using CTRL+SHIFT+F11,
2. Enter a new GUID in the field "Upgrades Product with Product Code" under the root Project node of the dialog.

Note: solution provided by Michael Nesmith, InstallAware Technical Support. A full description by Michael can be found at:

Cause:
I realize now that the problem was inadvertently caused by copying an existing project and using it as the basis for a new project. The end result of which was that the 'Upgrades Product with Product Code' GUID was the same in both projects.
Once I changed the 'Upgrades Product with Product Code' GUID the problem was resolved.

Hope this summary is of help to others!

Hi Steve,

That's brilliant - thanks. I had exactly the same problem (and probably exactly the same root cause - copying a previous installer project).

BTW, it's enough to just delete the "upgrades product with product code" GUID completely, unless it really is also upgrading an old project.

Cheers,

Ian, that's more or less the pitfall copying projects to "new" projects. I've done it myself a number of times and my butt has been bitten by an identical GUID. It's the same with plugins as well except there are more GUIDs involved.

If it appeared along with the other GUIDs on the main page, it would be easier to find and correct...
