Wrong and persistent VISA driver

[Pierre_F]

We used to develop all our company applications with labview 2015 and 2015 drivers.

One day I wanted to test NXG, and the installation squeezed lots of 2015 drivers by replacing them with 2018 drivers. when uninstalling NXG the 2018 drivers were persistent.

problem: VISA 2018 doesn't work with windows 10 when compiled from labview 2015. so my new application doesn't work anymore.

I know it because I tested different VISA versions on a previous program. I was forced to use 2015 in order to make them work in W10.

problem(2): I uninstalled the 2018 driver, but it is persistent, even if I reinstall the 2015.

-in every project I deploy, with or without VISA nodes, I have no choice but ticking "VISA 2018" in the installation menu.

-even if I manually remove VISA from Programdata\National Instrument\MDF\productCache, the 2018 is stil suggested.

I cannot use another version of Labview. does someone has a solution?

thanks in advance
