Problems with new version of Reactor

Hi,

I get the following error message in the 5.3.0.2 version of Reactor, if I select the combinatorial options on the 'Set reactor options' panel:
 
Reaction failed
 
chemaxon.reaction.ReactionException: Starting concurrent executor threads failed or concurrent processing error.

I used the previous version of Reactor, I had no problems with it. I have 1.6.0_17 Java version.
Anyone know how to fix this?

Thanks,
Norbi

Hi,

We will fix this bug ASAP. As far as we know the bug only occurs on Windows OS, when running the Reactor GUI application. The bug is not reproducible on Linux, and the Reactor command line application works on all operating systems.

Please use the command line application, or run Reactor on Linux OS until we fix this error.

Sorry for the inconvenience.

Zsolt

Hi Zsolt,

Thanks for your fast reply.  Until then I'll use Reactor on Linux.

Best regards,

Norbi

JChem 5.3.1 contains the fix. It can be downloaded from here: https://www.chemaxon.com/download/jchem/
