If you uninstall any NI products using Native Access, ALL programs listed in the "Uninstall or change program" section of the Control Panel disappear!
You can't uninstall or change any other programs…
Moreover, you can't open files directly, since you get an error message "This action is only valid for products that are currently installed" (although they are installed). You have to open the apps first…
I still haven't found a fix to this, I'll probably have to reinstall Windows…
Just wanted to let the community know.
