how do i remove a certificate from .exe or .appx












0















In sign tool I'm getting the error: bad executable.



I'm sure this has something to do with the application already being signed.
How do I remove the signature from the application.
I made it by unreal and I've heard unreal automatically signs the app on export.



I also heard if you change the extension to .zip, and then back to .exe or .appx, it will remove the certificate. But I tried that and had no luck.



By the way I don't use visual studio is there an straight forward way of doing this?



Thank you.

          This will help. It is a utility called delcert with soure code on xdadevelopers. It removes digital signatures (Authenticode) from executable files.



          Also check that you are running the correct version of the signing tool (32/64 bit) for the executable you need to sign.

          • Hi thank you for your reply. Delcert removes the certificate but im still getting the same error of bad executable. My app is a 32 bit so im using the 32 bit sign tool
