How to install multiple instances?

I have tried and tried to install multiple instances and cannot get it to work. I use KIAUH and once i delete klipper , moonraker, mainsail, and crowsnest it will not allow me to add klipper back on again. I got it to work once and then I was able to reinstall everything back on and when i rebooted the pad 7 it would no longer boot back up again. There seems to be so many issues and I am starting to think it is related to the last few updates with klipper , moonraker etc. I also tried reflashing Cb1 OS on the pad 7 and used V2.3.2 and this is also not letting me add more than 1 instance. Anyone else having these issues?

Reproduce the reported installation sequence with KIAUH on the Pad 7 using CB1 OS and version V2.3.2, including removal and reinstallation of Klipper, Moonraker, Mainsail, and Crowsnest. Compare the result with a single-instance setup and test whether the Pad 7 boots after reboot; done means multiple instances install successfully and remain bootable.
