Here is a quick reminder, the current release of VistaGlazz is not compatible with Service Pack 1. It’s wise to unpatch your system before installing Service Pack 1. Do not use VistaGlazz (1.0) on a Vista system that has Service Pack 1 installed.
We are working on a version that is Service Pack 1 compatible.
In the meanwhile you can patch your system manually. You can find the files here:
