"Another installation is already in progress"

[mathieu]

Hello,

i'm trying to add .NEt framework as a pre-requisite to my app.

Pre-inttall prerequisite forces me to use the exe bootstraping technique, i don't want that.

Feature based pre-requisite gives me the error : "Another installation is already in progress" during the installation.


I've selected "MSI type install" in builds.
I've included the .Net framework in my MSI.


What am i doing wrong?

Hello,

Please note that we recommend installing.NET Framework as a pre-install prerequisite. You could find more details in this FAQ article : Why does .NET Framework fails as feature-based prerequisite?

Hello and thank you for your answer. I wasn't aware of that FAQ.

Does this mean that instaling .NET framework as a prerequisite forces me to use an .EXE bootstrap instead of the MSI type?

Hello,

You are welcome!

Unfortunately in order to be able to start the installation of a prerequisite before the main installation process the exe bootstrapper is required by the pre-install prerequisites.

Thank you for your answer.

In that case we will probably just warn the user that the sub-components will not work if he doesn't have .NET framework 4.5.2 or higher.

Is there a way to show such warning dialog based on the fact that the user has that .net version or not? I'm guessing maybe something with custom actions and custom dialogs?

Thank you.

Hello,

You are welcome!

For this you could use a Software Launch Condition. Just go to "Launch condition" page, "Software" tab and select ".NET Framework".

In this way the package will only be installed on systems that have the .NET Framework installed. Else a warning message will be displayed and the installation will be terminated.

Best regards,

Even with 2019 version (v16.3) of Advanced Installer - the "Another installation is in progress" error shows up EVEN when the the exe bootstrapper is used.

Hello and welcome to our forums,

Can you consistently replicate this behavior on multiple machines?

Occasionally this error could occur if there is another installation in progress while you are trying to install your setup product. For instance you can try to search and see if there are any Windows Updates installing silently.

All the best,
Daniel
