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

Return code: -1073741819

Press 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.
