At first i had the exact same problem than @ilonapshe
My setup is a KVM/QEMU Win11 LTSC IoT Enterprise running on Arch host.
I tried to install the program from spice folder share on host, turns out the folder share doesn't like too big files so my error was there. Couldn't even copy the files from the shared folder to the guest. So i copied the files to USB drive and directed that to the guest, from there the installation was smooth sailing.
Then i had the Vida couldn't start error because port 80 was in use. The error message was helpful and i found in the thread that @repeq had posted about stopping and disabling World Wide Web Publishing Service from the windows services.
After that everything seems to work nicely i still need to see how it works with my cheap chinese Dice but maybe i just get the J2354 as it would be better anyways.
Thanks for the great work you have done @ZaanTerror , this truely is the silver bullet to solve all Vida installing problems!
