I created an EXE application from a LabVIEW project. From this application, I made an installer. I tested it on another PC and there weren't any messages. The program was provided to the customer. During the installation, by pressing the setup.exe it pops up a message "You must install LabVIEW 2020 64-bit on the system before you can run this setup"
. The PC on which the installation fails is however a Windows10 64 bit.
