Sigil Installation on Windows Arm64

mk14steve · 12-16-2024, 12:19 AM

Does anyone know why Sigil installation stops if installing on Windows 24|H2 on an Arm64 processor and it says can only be installed on x64 machines? Microsoft have included an "emulator" in Windows 24H2 that allows regular x64 applications to run on Arm64 processors (in much the same way as the WOW layers allowed 32 bit applications to run on 64 bit processors). It is called Prism. I think Prism intercepts the x64 bit instructions and spits out Arm64 instructions to the cpu - something like that anyway. It is quite transparent to the user, it just works and on my ASUS vivobook S15 Arm64 machine and other x64 applications I have installed work a treat. Prism doesn't work on drivers however.

I am wondering what Sigil is doing that won't run on windows 24H2 on an arm processor?

If all that has happened is Sigil developers have "assumed" it won't work, but not tried it then I would like to. Any chance? If it has been tested and failed, an explanation would be nice. Off hand I can't think of anything Sigil might be doing that would not run with Prism.

There's a good chance I can fix this within the Windows installer for Sigil. I can prepare a beta to be sure. I'm just trying to figure out the best way to solve this within Sigil's source so that it doesn't force those who build their own versions of Sigil to update to the latest Inno Setup.

I've got a Windows Beta installer ready to test if it works on Windows arm64. Sigil still needs the Microsoft Visual C++ 2015-2022 Redistributable (x64) to run. I have no idea if that is installed by default on Windows arm64 or not. It's been a part of x64 Windows since Windows 10, so it's no longer included with the Windows Sigil installer.

You can download the beta from my personal github repository: https://github.com/dougmassay/win-qt...s/tag/v5.212-1

It's the asset named Sigil-2.4.0-Beta-2-Windows-x64-Setup.exe

It's a tad bit bigger than the official release versions because I don't take the time to ultra compress betas or Continuous Integration builds.

Please let me know if this is enough to let Sigil install and run on Windows arm64.

Yep. Installs a treat on my ASUS Vivobook S15 with snapdragon X Elite Arm64 processor and windows 24H2. Good old Microsoft to think of Prism! (They had to really or no one would buy an Arm64 laptop if they couldn't migrate existing applications until everyone caught up).

It runs OK and I am able to create a new epub and edit an existing epub (both epub 2 & 3). Not done extensive testing of all functions but so far it looks good with what I use most. Calibre works also, so I can convert to and from other formats easily enough too. Brilliant.

For a minute I thought I would have to build my own Sigil from source using the instructions on the Github page. Not something I've done before but was willing to trawl through it and figure it out if it was the only way to get a working copy. I know that MS Visual Studio 2022 includes support for Arm64 (has done for some time) and there's an ARM64 installer for Python 3.12.8(it says experimental but works) so I figured building from source might just work. I might still do that just to see if I can.

In the meantime I can move forward and do what I need with this Sigil beta release. So far no issues arising. Thanks for this.

... doesn't show up.... don't know why ....

Yes, everything installs ok and the application runs ok. Looking good so far.

Thank you! I just was looking for this as I had the same problem. It works a treat!

New users sometimes have to suffer through an arbitrary number of posts before things stop being moderated. It's an anti-spam measure. Your reply has been manually approved (and you should be well on your way past the post count necessary to avoid auto-moderation).

Thanks for letting me know the beta installer works. Subsequent releases of Sigil will have this fix in place.
