Re: Conda installation on Windows broken, both minconda & radioconda installer (Was: Please help out a new guy)

[Ryan Volz]

Hi Dave,

I see you've found the relevant GitHub issue for this:
https://github.com/ryanvolz/radioconda/issues/78

It's still unclear to me exactly what is going wrong here, but it is 
certainly some form of having multiple versions of a library on your 
system (probably Qt, probably installed with other software) and those 
conflicting with each other. Conda environments try to isolate these 
things, but clearly it doesn't always work. Windows, in particular, is 
harder with how it handles DLLs.

The best advice I can give is to try uninstalling other software that 
might make use of Qt.

I won't have a lot of time over the next month to look into this 
further, so sorry ahead of time. It's a high priority issue though that 
I plan on tackling further at some point. Maybe someone else who can 
reproduce can step in and help out until then.

Cheers,
Ryan
