How to run OneCollect 1.9 on Windows? max_workers must be <=61

brontobyte — Wed, 04 Jun 2025 11:14:34 GMT

Anyone have any idea how to get past this error? It occurs whenever OneCollect.exe is run. I'm using 1.9 on Windows.

max_workers must be <= 61

Is there a configuration setting that can be updated to set the max_workers below 61? I've found nothing helpful in the documentation and further research suggests solutions that don't appear to be applicable after it is compiled.

Error:

max_workers must be <= 61
max_workers must be <= 61
