Konu: Re: [Chimera-users] I need older version
 
Hi Dilara,
Chimera is compiled on Windows 7 and should run on Windows 7.  If you’re actually talking about ChimeraX, that does not run on Windows 7 but Chimera should run on Windows 7 without any problems.

Good days,
Thank you for your usefull protein preparation options. I have a problem when setting the Chimera in my Windows 7, 64 bit computer. Because of this old version of Windows Chimera can not be established. Is there any older version of Chimera to set on Windows7? Before 10 years, I used chimera on Windows7 but now it is not available.
Please help me.
Best regards
Dilara Karaman
