How To

The "Error 5 – Invalid procedure or argument" message in LEAP when working with Word documents is often caused by incorrect regional or system locale settings.

To resolve the issue, follow these steps:

Press the Windows key + I to open Settings.
Navigate to Time & language > Language & region.
Under Region, ensure the Regional format is set to English (Australia).
Scroll down to Related settings and click Administrative language settings.
In the new window, go to the Administrative tab.
Click Change system locale... and select English (Australia).
Confirm the change and restart your computer if prompted.

Once these settings are updated, the error should no longer occur.

This may also resolve display issues in LEAP Accounting where figures appear as "<<<" instead of actual numbers due to incompatible regional formats.
