I can no longer install Synapse 3 - error code 142

Reading this thread /error-142-solved.59237/ I understood that the problem occurs with defender protection, so I've put the folder C:\\WINDOWS\\Installer\\Razer Central\\RCUninstall\\ in exclusions of Defender, and I was able to install it, however I don't like the idea of having a whole folder that is not checked by Defender, so after installing I removed it from exclusions. I noticed that the uninstall.dat and uninstall.xml that the Synaspe installer puts in that folder are not signed, maybe that's why Defender prevents them from being installed? If so I think Razer should make them signed, and not force the user to disable the protection, or put the folder in the exclusions as I did.

Currently synapse 3 uses windows api such as (KERNEL32 HOOKS, ws2_32 NETWORK, fileapi, and more ) which most good security solutions keep an eye on the user's system. and if not signed trust is highly suspicious of illicit activities, I don't know how this improperly not properly signed trust.
