Software Deployment

This is the event log for one of our machines this morning:

Event Type: Error
Event Source: MsiInstaller
Event Category: None
Event ID: 11705

User: SYSTEM

Description:
Product: DM with no Active Integration -- Error 1705. A previous installation for this product is in progress. You must undo the changes made by that installation to continue. Do you want to undo those changes?

This package was originally installed from here:

\\bcscnet.ca\dfs\dist\apps\CLIENT\Hummingbird\DM Client 5.1.0.5 SR 6 WITHOUT Active Integration\DM with no Active Integration.msi.

The Product Code GUID for the DM with no Active Integration.msi now sitting in this folder is "different":

{32CE6DCB-F2C8-4DCB-8AD5-23A76503295E}

I made a mistake editing the msi package and saving it - thus creating a new GUID.


Active Directory is attempting to remove this package and I think the different Product Code GUIDS is causing confusion.

When a user restarts their machine they get a message attempting to Remove DM 5.1.0.5 SR6 without Active Integration and it just hangs for ever!. Unplugging the machine and getting the user back on line seems to work. However a better solution is required.


Solution:

Here is some info from InstallShield

Product Code

This code should only be changed if significant changes are made to the application - changes that warrant to call it a different product. If you are just releasing a new version of your program, the product code should not be changed. Of course, two different products should never have the same product code. If you have two flavors of a product, say "YourApp Express" and "YourApp Professional", these should have different product codes. The same is true for different language versions of a program - they must use different product codes. Windows Installer cannot install two instances of the same product (i.e. two msi packages with the same product code) on the same machine.
Using different product codes is required to allow two applications to coexist on the same computer. If you try to install two msi packages with different package codes, but with the same product code, you will get an error message as shown in figure 1.

Figure 1: Reinstallation error message

To overwrite the existing product with a newer version, you should perform a small or minor update. This requires that you set the following properties on the msiexec command line:
msiexec /i Yourapp.msi REINSTALLMODE=vomus REINSTALL=ALL
The important part is the "v" in the reinstall mode settings. It forces the use of the new msi file instead of the cached copy. Therefore it can't be set inside the package. The rest of the REINSTALLMODE flags make sure that existing files get updated, new files get installed, registry entries are re-written and shortcuts are created. REINSTALL=ALL means that only those features, that were selected by the user during the install of the old version get updated. Unselected features should not be added.

Here is the code for a possible batch file for our user and others:

msiexec /i "\\bcscnet.ca\dfs\dist\apps\CLIENT\Hummingbird\DM Client 5.1.0.5 SR 6 WITHOUT Active Integration\DM with no Active Integration.msi" REINSTALLMODE=vomus REINSTALL=ALL

Any thoughts or comments on the best way to stop this active directory "removal" process.

On fresh new builds of machines the new GUID {32CE6DCB-F2C8-4DCB-8AD5-23A76503295E} installs just fine - it is the old machines that seems to be caught in a state of limbo!

Thanks for any help on this - it has been a few stressful days on late.
