Runtime error when modelling dendrimers

Sorry to repeat this already discussed problem. But when trying to modelling a dendrimer (20,000 Da) I receive this message

"Runtime Error!

Program C:\Program files …

This application has requested the Runtime to terminate it in an unusual way
Please contact the application’s support team for more information"

Could anybody help me??

Thanks in advance and sorry for repeating the topic

I don’t think it’s an “already discussed problem.” But can you be a bit more specific?

What are you trying to do, and when does the error occur? Saying “modeling” doesn’t help much.

  • Does it happen when you’re building up the dendrimer?
  • Were you optimizing the geometry?
  • Were you opening a file with the dendrimer molecule?
  • etc.

Can you please be precise about what version of Avogadro you’re using, what version of Windows, and what happened?


Sorry, this happens when I am optimizing the geometry, just then. I am using Avogadro version 1.1.1. Perhaps is a matter of the amount of atoms??..more than 5.000 ??, then my computer is not capable of calculate???..

I am using windows 10, 64-bits, and my computer is not excesively old, Intel Core i7-2600 CPU @ 3.40 GHz, 16 GB RAM,

Could I send the xyz file so you can have a look?

Thanking you in advance
