3. Install NVDA

Does the issue still occur after restarting your computer?

Yes.

Have you tried any other versions of NVDA? If so, please report their behaviors.

No, only newest.

If NVDA add-ons are disabled, is your problem still occurring?

I have not tested any add-ons, only the default installation.

Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?

Not tested.

This is 64-bit voice only. Thatš why it only works with narrator.

When will NVDA support 64-bit voices?

@snomos - we are migrating to 64bit this year, we should have support in 2026.1
