Developer ID Application/Installer: no identity found

I have two certifications in my keychain. One in my "login" keychain which is: "Developer ID Installer: My Company"

I then have a second certification in my "System" keychain which is: "Developer ID Application: My Company"

I am trying to codesign my installers. I have a script .app file called "Step 2 Installer.app" When I try to codesign my .app file I get the "no identity found" error. My keychains are definitely valid, not expired, and have their trust settings to be "Always Trusted"


codesign --force --sign "Developer ID Application: My Company" /Users/mycomputer/Developer/Packing\ Materials/Step\ 2\ Installer\ 2.app



Any help of suggestions would be greatly appreciated.
