<div class="moz-cite-prefix">Yes, you can reinstall an earlier
version of Chimera. Multiple versions can be on your computer at
the same time. But first, try running Chimera's Tools / Utilities
/ Browser Configuration tool to reassociate .pdb files with
chimera. And as you know, you can always use Chimera's Open
dialog.<br>

<div>Hello,<br>
</div>
Warm Greetings!<br>
</div>
Thank you for Allowing me to use Chimera through
academic license.<br>
</div>
Yesterday(June 2nd) I was prompted to update
Chimera to 1.9 version.<br>
</div>
I accepted and installed it successfully on my
system (windows7pro). Before that I had removed
Chimera 1.8.8.<br>
</div>
The problem I face is, I can not open certain
.pdb/.pdbqt fies saved in my comuter. such files even
do not exhibit chimera logo which earlier version did.
Even with "choose default program" system can not
open these files insted other program (like spdbv)
open them.<br>
</div>
I have not made any change in my system after installing
new version.<br>
</div>
Can I reinstall earlier vrsion(1.8)? <br>
</div>
Kindly suggest me what best I should do to avail service
(Academic Research) of chimera again.<br>
</div>
Regards. <br>
