Wrong compatibility declaration

[CyrilleB79]

Issue

The add-on claims to be compatible with NVDA 2019.3 onwards.

Testing with 2023.1, I get the following error at startup:

ERROR - globalPluginHandler.listPlugins (09:51:31.598) - MainThread (1496):

Probably because the .pyd file is a Python 3.11 one, not a 3.7 one.

Solution

• Either fix the issue with older NVDA version and recheck it with them. For example, add both the .pyd for 3.11 and 3.7 and configure the import path according to Python version
• Or reduce compatibility range

Thanks for the report. Someone else already mentioned that to me and the fix will show up in the next release (hopefully this week).

The reason for the incompatibility is, as you surmised, the switch to python 3.11.
