DDL could not be run during Windows installer package.

[Chricolomba]

Hello everyone.

I have created an installation package containing the application for the customer.
I have tried to install the application on different computers within my company and it works perfectly.
But when the customer tries to install the application it does not work and shows the message in the following picture.

I cannot therefore understand why on our computers the installation of the software does not cause any problems but on my customer's it does.

Initially I thought the problem might be related to this:

But from what my customer says, the situation does not change even if he follows the instructions shown in the link.

I would be very grateful if someone could help me, in the meantime I wish you a wonderful day.

What LabVIEW version do you use to create the installer? What other packages and their versions from NI did you also install on your computer?

What OS versions did you try it out in your company? What OS version is the customer trying to install it on?

First of all, thank you Rolf for your quick reply.

• To create the installer I use the LabVIEW 2020 SP1 32-bit version
• These are the packages that are installed on my computer. Note that on the same computer I have labview 2015 2016 2017 2018 2019 and 2020 (all SP1 and 32 bit)
  
• In our company we have Microsoft Windows 10 Pro
• From the design of the screen capture sent to me, it would appear to be Microsoft Windows 10

I am aware that due to version 21 the application cannot run with Windows 7 any more, but it would seem that this is not the case.

Thanks again for your help.

It's not just Windows 7 that is not anymore supported. It's any 32-bit OS that won't be supported. Even though Windows 10 32-bit installations seem very very rare, you need to make sure about that.

My computer and that of my colleagues (who do not have any NI software installed) are running Windows 10 64bit and do not show the problem that appears to the customer.

I don't know where to hit my head anymore. Could the problem be the software packages that have version 21? I have tried to downgrade the visa package for example, but I still can't get back to version 20.

As soon as you install anything from NI that has version 20.7 or newer the according build tools to create installers are updated to not support creating installers that can be executed on 32-bit systems AND also prior to Windows 10 1507 no matter if it is 32-bit or 64 bit.

This knowledgebase article points out a possibility to modify the according setup.ini file if your installer builder still creates an MSI based installer. For NIPK based installers the only way to support building for 32-bit systems is by downgrading the NI MDF to 20.6 or earlier. And that may not be a solution if you have certain software from 2021 or newer installed.
