Keytar + Electron: Works on OSX, "Error: %1 is not a valid Win32 application" on Windows

[tylerjames]

I added Keytar to my Electron app and ran electron-rebuild on it. After packaging the resulting app works just fine on OSX, but when I try to run the .exe on windows I get the dreaded:

"Error: %1 is not a valid Win32 application"

I read that this might be due to the module being built for x64 which makes it not run on an ia32 environment.

So I installed node-gyp and rebuilt the module using:

HOME=~/.electron-gyp node-gyp rebuild --target=0.36.2 --arch=ia32 --dist-url=https://atom.io/download/atom-shell

It built fine but I got the same result after packaging the app for win32.

Is there any way to get this running on a 32-bit windows environment? Am I doing something wrong when in rebuilding step?

I can see that keytar is at least included inside the app folder after packaging. Is there a way to tell what architecture keytar was built for?

Thanks in advance for any help.

I'm running into the same issue, but I'm also not sure how to fix it.

i got same error and managed that.
You may run 32bit of keytar on 64bit of electron.
To check which arch the node(electron) is running on:

console.log(process.arch);

also check out electron-rebuild for building module instead of using node-gyp directly.

rebuild with electron-rebuild works for me

.\node_modules\.bin\electron-rebuild.cmd -w keytar -p -f

I am still running into this while building a windows package on a Mac OS. Is there a specific way keytar needs to be rebuilt if doing this?

same error for me

In my experience, I had to build the Windows version of my electron app on windows in order for modules to be compiled and packaged properly. So, I built my package for Mac on Mac, and the windows app on windows.

I don't think this is necessary if you don't have any native modules. In that case you can build and package on one platform for all platforms. But for native modules, I was only able to get it to work by building and packaging on the same platform that I'm targeting.

I've heard that you might be able to use wine on mac to build and compile native modules into electron apps. I tried it, but it didn't work for me.

Microsoft provides free VM you can use for these purposes

Running electron-rebuild with yarn electron-rebuild seemed to do the trick for us in the end. We were trying to run electron-rebuild with a specific version, which did not seem to play well with keytar.

TL;DR:

• Make sure you're compiling on a windows machine
• You will need windows build tools installed to compile modules on windows.
• If you're having issues with keytar, install electron-rebuild and run electron-rebuild in the folder of your app with the command $(npm bin)/electron-rebuild or yarn electron-rebuild if you're using yarn.

same error

Getting the same error. electron-rebuild had no results.

[surajreddy]

@xp6530 @levinunnink can you try deleting your node_modules directory and trying again?

As I read here, there is nothing to do to compile an electron app for Windows from macOS and compile the Windows version should be done on Windows ? Right ?

If no, could someone help me ? I've the "Error: %1 is not a valid Win32 application" error from the first post who the app works fine on mac but not in windows. Trying electron-rebuild but don't works..

Hi all, did anyone have any luck with this? I'm hitting the same error and have tried all the suggestions above. Thanks

@jamarw user keytar-prebuild ! See #67. This works for me.

Thanks @popod ! Appreciate the help.
