Hello. I've used Chimera for a year, but I can't start Chimera suddenly.I deleted the old version, and installed the latest version, chimera-1.13.1-win64.But it showed the same error.When I start chimera, I got this message.--------------------------------------------------Cannot execute 'gzip': no automatic decompression of .Z files initializing general preferencesloading Tixinitializing graphicsReturn code: -1073741819Press return or enter to to exit----------------------------------------------------I found the similar error reported previously. (http://www.cgl.ucsf.edu/pipermail/chimera-users/2011-December/007021.html)So I ran the dxdiag program on my computer and attached the file including all information from dxdiag.I will be grateful for any help you can provide. Best wishes,Jimin Park.
