Did Chrome change CRX format recently? Getting "crx_header_invalid" error. 0 Recommended Answers 23 Replies 325 Upvotes
I wrote a Chrome extension for work long ago. It has worked for years. But today, trying to install it on a new computer, Chrome reported "crx_header_invalid". Did the CRX file format change recently? I see no notice of such a change, but when I regenerated the CRX from the original app using a current version of Chrome, it worked again.
Does anybody know if the CRX format changed recently, or if signing policies have changed, or something else?

Same here. As soon as I updated to Chrome version 73.0.3683.86 (Official Build) (64-bit) this started happening to me as well. Looking for a workaround as we speak.

Tim Bessie your post here actually led to my solution. I was getting this same crx_header_invalid error, for brave browser then I did this (in the link) --which is what you're saying-- with the latest version of chrome https://www.cnet.com/how-to/how-to-install-chrome-extensions-manually/ and it worked.

Stanford - I'm glad this helped; unfortunately, the problem isn't the method of installation (my Chrome app isn't in the Chrome Store, it is always installed manually); the problem is apparently someone changing the Chrome CRX file format without notifying anybody (at least, I can't find mention of it anywhere on the Chrome developer groups/sites or in any release notes). This is a BIG change and should have a BIG notice.

What actually changed was that in the newest Chrome version, CRX3 extension packing format is now enforced. So, the extension you are installing needs to be repacked in CRX3 format.

I'm experiencing a similar issue, with a slightly different error message: CRX_REQUIRED_PROOF_MISSING
Installing a crx works for some people but not for others.

For devices that are managed (by a school or business for example), you cannot switch into dev mode. Is there a way around this for it to still work?
