Ah, I see the problem. It is trying to print the start of the Modeller 
log file, which has information on the Modeller version and environment. 
Position 957 is about where your computer name is. We assume that name 
is valid ASCII or UTF8 (and nobody's reported this error before!) but I 
suppose it doesn't have to be, particularly in non-Western locales. 
We'll fix this issue for the next Modeller release. In the meantime you 
could work around it in one of two ways:

1. Change your computer name in Control Panel to something containing 
only plain ASCII (e.g. try "XXX") and reboot.

or

2. Edit logger.py in your Modeller installation, i.e. 
D:\conda\Library\modeller\modlib\modeller\util\logger.py and change line 
8 from

     _header = _modeller.mod_header_get()

to

     _header = ' '
