You can use this instead:

$PropValue = AI_GetMsiProperty PROP1
write-host "$PropName = $PropValue"

And this is the whole problem: I don't know exact property name to read at compile time, it is determined in runtime based on other properties. Here is an example:

I have a bunch of properties ...

Now I understand how AI_LISTBOX_DATA works. I eventually split listboxes in different dialogs. My approach now is as follows:

1. Have UI sequence script which pre-calculate all listboxes at wizard launch and store them in temporary property
2. In dialog initialization actions, copy value from temp ...

I have a custom action (UI sequence) that writes some property, say PROP1:

AI_SetMsiProperty PROP1 "Some value"

Then in some UI dialog in init actions, I have another custom action (no sequence) which reads same property:

$PropName = "PROP1"
$PropValue = AI_GetMsiProperty $PropName

Note ...

Hi Liviu,

Thanks for your response! This is a very unfortunate behavior. The problem is that both listbox population logic share a lot in common, just slight differences and splitting them into separate scripts will cause a lot of duplicates and will be hard to maintain.

BTW, why do I need "Delete ...

I have a custom dialog with two listboxes. They have property names "LB1" and "LB2" respectively. Then, I have a powershell script in UI sequence:

AI_SetMsiProperty AI_LISTBOX_DATA "LB1|val1|val2"
AI_SetMsiProperty AI_LISTBOX_DATA "LB2|val4|val5"

and I added a PopulateListBox helper action. Then ...

Catalin, thanks for your response it explains some of my observations during testing. But I have a couple of other questions related to this.

Ok, Advanced Installer tool is per-machine and requires administrator permissions to install it. Then, I would expect the following workaround to work, which ...

We are using Advanced Installer to build installers using Azure DevOps and generally it works like charm!

However, we found a problem when we moved from cloud-hosted to self-hosted agents, when we run build agents on our VMs. We use least privilege principle and didn't grant the agent account ...

Understood. Anyway, thanks for assistance!

This is very unfortunate behavior. Major upgrade strategy for smaller products is the most convenient way to update the product.

And for many aspects in AI it is possible to define task execution conditions. Services are not changed often even during major upgrades. Service executables -- they may ...

Custom PS scripts aren't encrypted, they are encoded and you can easily recover the script using PowerShell. Copy encoded string from XML tag value to clipboard, then in PowerShell console insert copied base64 string:

$base64 = @"

The ProductCode should be the same for the recache operation I've mentioned, not for installing the new MSI over the old MSI.

understood. I have to keep same product ID and upgrade ID in order to re-cache the installer.

Our application installs the Windows service along with install process. By default we configure the service to run under "Network Service" account, it is configured in AI project.

However, we treat this as default installation and recommend (though not requiring) customers to use gMSA service ...

Hello Catlin,
thanks for your fast response!

That probably happens because you have changed the ProductCode property and now Windows Installer sees your MSI as an upgrade.
this may happen since we use Azure DevOps pipelines to build the MSI. It appears it re-generates the product code every time ...

We have an MSI package which includes custom actions executed during install and uninstall to configure certain things on install and roll back on uninstall. However we detected a major flaw in custom action script executed on uninstall.

My aim is to fix the MSI (only custom action, all other ...

That was it! I have no idea why I tried to call misexec against .exe, must be some mind eclipse.
