The new version doesn’t want to update an old one and shows a message: «Update error». At that the problem cannot be solved even if we delete the whole body from PKG file and the title take from PKG file of the previous version. But it’s possible to install the old version over the installed new version. Also it’s possible to install the new version after the deletion of the old one.
1. The certificates in both versions are similar.
2. The old version includes two inserted SIS files. The new version doesn’t include inserted SIS files.
Please, help me to solve the problem.
