Change decimal separator

I have the same question for Quickbooks Desktop Pro 2019 and Windows 11. I have done everything you mentioned, rebooted the system and even reinstalled the QB afterwards, but still nothing changes.
What else is there to do?

Have you tried what Fiat Lux shares?

Where do you live? You can ask them to schedule screen sharing to help if needed.

I can see the challenges with changing the decimal separator from comma to point in QuickBooks Desktop (QBDT),  @EthylicCedric. I'm here to help you resolve this matter.

We must enable this feature in the company preferences if you want to use the decimal point. By doing this, QuickBooks adds a decimal point to the item quantity automatically. You can take the next few steps to enable the decimal preference.

Here's how:

1. Launch QuickBooks Desktop.
2. Navigate to the Edit menu.
3. Click on the Preferences and click the General section.
4. Once you get into the My Preferences tab, you can place the checkmark for the Automatically Place Decimal Point tab.
5. After this, click the OK button.

Additionally, You might want to use some form templates so you can modify the details. QuickBooks contains the customization tools you need to make them so. Refer to this guide to complete the process: Customize Form Templates.

Hi,
I am in Hong Kong. I did everything that Fiat Lux suggested, but it didn't help. In the Windows 11 language settings I have 123,456,789.00 and QB writes 123 456 789,00. Because of this the export of reports to Excel fails.
Also, I am using a bilingual OS.
Thanks.
