Failing to restart install on reboot

I'm having an issue where our installer installs some C++ redistributables then says it needs to reboot. You accept it, let the computer reboot, and then the installer simply does not continue. A few of my coworkers have investigated and it appears InstallShield is putting the value in the RunOnce registry double double quoted ""like this"". It also appears, this only causes a failure when the installer has a space in it. Installer.exe works fine, Installer (1).exe fails. Is there any way to fix this?

What version of installshield you are using IS2018 or 2020 or 2021? Could you please provide a screenshot of your Help > About InstallShield screen from your copy of InstallShield that you are using to configure the affected project? This allows me to match the InstallShield service pack level and edition

Are you facing this issue in all machine or only specific machine?

2018 R2. It happens on many machines which is why we noticed it. My coworker's investigation suggests it happens when the installer has a space in it, but not when it has no spaces.

I can confirm this is a problem for us too - I never knew what the problem was, but having a space in the setup .exe name is the issue!
