native access 3.6.1 -> 3.6.2 (chicken and egg)

Back in October 2023 , when post that you refer to were written, then there were a specific issue with updating Native Access where , quote : 'cure' for that one is to download latest N.A. installer and install it on top of old / previous version !

Also, historically, there has been problems for some users where not even uninstalling the old Native Access were enough to make sure that the re-install would work correctly and where systems apparently needed a deep scrub to be free from old version before installing the new version.

Concerning Native Access and Windows , and Windows in general then problems installing something nearly always are 'access problems' though the reasons for these access problems may vary from situation to situation, from lack of basic user privileges to problems with file already existing and being locked for some reasons !

Generally speaking though then, at the moment as of February 2024, then if you are already using a close to newest version of Native Access then Native Access usually will not have any problems updating. However, if you have any problems updating Native Access or you suspect that you might have any problems then the standard procedure would be to uninstall Native Access and then on top of that use the N.I. reg tool to remove all traces of both Native Access and the NTKDaemon.

Again , as implied in the above then you will also need to run both tool and installers as an Admin and be sure that you have sufficient access privileges to the computer.

I hope that it will work for you. Incidentally , on the subject of being careful , then when your computer works as you like then you ought always take a full image based system drive backup so that you have a backup to revert to if you ever have mishaps. System drive backups obviously however do not backup content not found on system drive !
