Hello!
I eliminate that simultaneously can exist only one session object in install.
Session object provide some handy opportunities.
Next code written in VBScript will show UpgradeCode values for every product, installed in target system:

| CODE |
| Dim oInstaller, sProduct, oSession Set oInstaller = CreateObject(“WindowsInstaller.Installer”) For each sProduct in oInstaller.Products Set oSession = oInstaller.OpenProduct(sProduct) MsgBox oSession.ProductProperty(“UpgradeCode”) Next |
But how I can retrieve it from CA?

It’s simple to receive ProductCode value.
Automation interface provide
I can perform it with code:

| CODE |
| Dim oInstaller, sProduct Set oInstaller = CreateObject(“WindowsInstaller.Installer”) For each sProduct in oInstaller.Products MsgBox oInstaller.ProductInfo(sProdCode,"InstalledProductName") Next |
Where "InstalledProductName" is specified attribute, which provide ProductName.
Can I receive UpgradeCode without Session object?

I don't think the upgrade code gets registered in the installer info similar to the product code for installed products. I guess you would have to open the MSI and read the contents of the property table.

But what I shall do if previous MSI file not available on target system?
I still can acquire UpgradeCode from Automation Interface by Session.PropertyName("UpgradeCode").
Thereby, UpgradeCode value stored somewhere in Windows Installer repository on target computer.
I suppose it possible to access UpgradeCode in this repository directly?
Thank you.

Problem I work on state, that I never know UpgradeCode before my MSI arrive at target computers.

Calling Session.PropertyName("UpgradeCode") in a custom action will give you the value of the UpgradeCode property of the running install,not of any other msi file on the machine. But if the setup isn't running and you don't have a session, you can't get property values this way. Instead I believe you would have to use Installer SQL to read the UpgradeCode property from the Property table in the msi file.

Thank you.
I hope MSI 3.0 provided with functionality that allow avoiding this limitation.
