This brings back unpleasant memories.  My firmware is 4.5.4.  In order to install 5.3 I apparently need 4.6.2 (according to the Wiki). Why the wiki doesn’t have a link to that is unfortunate.  A Google search finds the wiki but not the download location of 4.6.2.

Will one of you regulars point me to the download?  Hey, give me credit for reading the notes before upgrading to 5.3

Found this link.. it mentions upgrading to 5.016 from 3.x... also has a link to upgrade to 4.8, which may get you to where you want? 

But if you aren't sure, I would just open a ticket and as UD what is the best way forward./

UD lo longer offers support for the ISY994. There's no point in opening a support ticket.

Here's the link and update instructions for the ISY994 5.3.4 firmware

5.3.4 (ISY994) - Last release for ISY994 - Current Release Announcements - Universal Devices Forum

This will involve some user intervention. You'll need to check each program and scene for possible errors.

Before any update always make an ISY backup

Michel has been great over the years, but I wouldnt open a ticket because of the EOL.  I just get frustrated how trying to find specific firmwares is a needless hassle.

You can find links to all the available firmware in the forum here:
