Impossible to reinstall NI-IMAQ in oldier version

[Leakcim26]

Hello.

First of all I want to apologize for my English because I am French. I made a mistake installing the latest version of NI-Vision (VAS) 20.5.

The version of Labview I am using is LabVIEW 11 SP1. I wanted to uninstall NI-VISION 20.5 but it also uninstalled Labview 2011 SP1.

Subsequently I did a Windows system restore everything came back as before but I lost my Labview license (I see with National Instruments to be able to recover it).

The problem that I have just exposed here is that I can't install all the NI-IMAQ drivers because according to the windows installer the NI-IMAQ drivers that are installed are more recent. The problem is, I can't see them NI Package Manager. I have deleted the registries in the windows registry for IMAQ 20.5 but nothing helps.

Can you help me?

Hi,

What is the computer windows version you are using? And which NI-IMAQ drivers you wish to install?

You may using NI website to download the older drivers instead of NI Package Manager.

Hope you can get some reference from below KB:

Hello Leakcim26

I have faced the issue like that and, unfortunately, you need to make system formatting and reinstall your windows.

The reference files of NI software's is going to many system folders and many register paths and the only way for appropriate remove of NI software is doing it from NI Package Manager

Again if you have done some software removes by the any other way, you should make a formatting.

Also, if you haven't SSP, you will be not able to download IMAQ from the official web page. So you will need to request that software from NI technical support
