Hello, the installation this time was successful, I have installed Taggtool with Java 64-bit version, de-selecting Java component during the installation, without having to install 32-bit or any other Java, just keeping my JRE 8u45 x64. This is quite odd, because in this manner the installation should be exactly the same as the previous one, Taggtool without Java, but so it goes.
Why the installer of Taggtool without Java behaves differently from the installer of Taggtool with Java deselected?

Hello, my installation failed twice, the first time I installed in an alternative directory ( not C: ), the second in the default directory C: - The installer fails in activating the Taggtool Service, it says you have not enough privilege to run. I have Java RE 8u45 x64, so of course I installed Taggtool without Java. I am on a Asus Sabertooth X58, 24GB RAM, Intel Core i7-930. I have read Alain's post about installing 32-bit JRE, I think you shouldn't be forced to do that, the installer should work with 64-bit JRE in a 64-bit computer. I will give a try to Taggtool with Java.
