We have renewed the "Aspose.Cells.lic" and "Aspose.Words.lic" the steps that we did:
This is the message that we got when we applied the files: The signature is invalid.java.lang.IllegalStateException: The signature is invalid.
the steps that we did:
Please note, new licenses are signed with SHA256 but older ones were signed with SHA1. Either you may use your older license(s) with the old versions of Aspose libraries and newer license(s) with the new versions of Aspose. Or you may contact relevant team to get updated licenses (e.g. signed with sha1) which can work with both newer and older versions.
PS. I am working as Support developer/Evangelist at Aspose.
