Question

Self-signed Extension signature not valid on Windows 10

Hi to all!

I packaged a ZXP extension with ZXPSignCmd (self-signed certificate).

All works well on macOS, when I install the extension with zxpInstaller.

But when I try to install on Windows 10 I get this message:

After lots of digging, I found that the same signature works great when I package a different extension (one of the Adobe samples on GitHub), just throws this error with my extension - on Win 10.

Any help is greatly appreciated!

Hi yehudan37348595,

Have you checked to see if the debug mode is turned on or off on both the macOS system you checked it on that the Windows machine? Does the installation fail if you install via another method, like Anastasiy's Extension Manager?

Sometimes people run into problems during the signing itself. ZXPSign doesn't like invisible files in your directory (like a .github directory or a .debug file). Others report problems with Windows filepath issues, or using non-English characters or spaces.

Perhaps take a look at this blog entry, or our guide here, and see if those are helpful.
