@Sims8431 MediCat is no longer an ISO. But you can make it into a bootable VHD and load it via Ventoy or an iODD usb enclosure. If you want the 2019 October version that was still an ISO though, it's on that "bay" site, that I cannot say the name of.
@Sims8431 There is not much point to an ISO because it's now too large to fit on a DVD (hence why it was renamed Medicat USB) although I suppose it would fit on a Bluray disc, but barely anyone has a Bluray reader in their PC, especially the older PCs you're most likely to use Medicat on (because older hardware -> more likely to break down)
