Originally installed 64bit X6 GS. Now to many lockups and errors. What is the easiest way to install the 32bit X6 GS over the 64bit version?
Unless there is something really strange with your system, or you have printers or scanners that do not have good 64 bit drivers. you should not be getting lockups and errors in the 64 bit version of X6.
Did you install the updates? Help > updates will tell you if you are missing any. Also check for windows updates and install the latest version of .net.
Apart from that, you should try emptying the windows %temp% folder (either after a reboot, or use a program like cCleaner) and try to reduce the number of simultaneously installed fonts.
