Unfortunately I'm still having the same problem - stuck at "Please wait patiently for loading modules". Strangely, if I exit out and try to run it again I get a pop-up asking me if I want to install Norton, which suggests to me it's getting further the second time, but it never gets past "Please wait patiently for loading modules" even if I leave it patiently waiting overnight.
Can I ask which residual folders you deleted? I've found MSI folders in the root directory of my boot SSD, in Program Files (x86) and in the hidden ProgramData folder and deleted all of them, but are there any others? Also, when you installed from the MS Store, what did you do exactly? Did you run MSI Center as an administrator the first time?
Thanks, and I'm glad you got yours working, it gives me some hope that this can be fixed!
