[Chimera-users] Chimera error at start-up

Dear Chimera, I cannot open Chimer anymore in a computer (Windos10 64) where it was running until yesterday. I tried with no success reinstalling the program and installing the latestChimera daily release. The error that I get at startup says: [cid:cfb0a3aa-9306-42f0-bfd0-328d433ceb1e] If I start in debug mode I get the following error in a command window: Cannot execute 'gzip': no automatic decompression of .Z files initializing general preferences loading Tix initializing graphics Return code: -1073741819 How can I resolve this issue? Thanks Hernando ___________________________________
