Starting with the QWT iso or attaching it didn't work for me either, it didn't show up at all. I copied it to the windows VM and extracted the installer from it.
Btw, I just installed Windows 7 SP1 from an iso and installed all updates in just a few hours.(old Sandy Bridge dual core with sata SSD) After installing 7 SP1, or after installing SP1 if using an older iso, don't let it search for updates but instead install manually the April 2015 servicing stack update and then the Convenience Rollup.(https://www.howtogeek.com/255435/how-to-update-windows-7-all-at-once-with-microsofts-convenience-rollup/) After that, the number of updates still needed in order to be fully up to date is a LOT less. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
