My coworker accidentally reproduced the bug by uninstalling the version of chimera that those file types were associated with.  And we were able to fix it by using Chimera's Tools / Utilities / Browser Configuration tool (BC).  So one question, is did you use the BC tool before to do the file type associations?   My guess is that you did, so you'll need to keep using it.  And, another guess, is that if you only use the Windows GUI technique to do the file type associations, then that technique would continue to work with newer Chimeras.

Hi, I am attempting to associate pdb and mol2 file types with Chimera 1.8rc in Windows 7. I have tried to set it using the right-click>open with... option in Windows as well as through the control panel. I select the chimera executable, but it does not seem to accept it as a valid program, and it returns to the previous screen without adding Chimera to the box for selection. I know this is not a Windows issue, as I can set other programs and it works fine. As well, I can set other programs for the mol2 and pdb file types. Is this a known issue, is there any work around. It's not the biggest deal, but it would make my life a little easier if I could do this. It used to work in the past, but just not with the latest version. Thank you and have a great day!
