Right-click it and select Clear Signature.
When I right-click my only options are "Validate Signature," "View Signed Signature," and "Show Signature Properties."
I have the same issue. When I right-click, the only options I get are Validate Signature, View Signed Signature, and Show Signature Properties. There isn't an option to Clear Signature. How do I get that option to appear, please? I've tried exiting and re-opening the program, but it doesn't change anything.
I am sorry for the delay in response.
