I run DOpus as portable software on a USB stick; the save, restore options and export to a USB stick are greyed out. But, when I go to the Help menu / Look for updates, if there is a new version available, I get the Install button. So, I noticed that if I press it, it would download the official installer and this installer would try to install DOpus on the HDD, which is not my intention since I run DOpus from the USB stick.
So, in my opinion:
- either you disable the Install button on the portable version since the installer doesn’t know how to update a USB stick (a quick fix)
- or you allow the installer to update a USB stick (I would prefer this option)
