Improper placement of thousand separator error in gINT Input

Problem

I'm seeing an error message like this

Solution

  1. Close gINT
  2. Ensure in Windows is using "." for the decimal place and "," for the thousand separators; This is done in Control Panel\All Control Panel Items\Region
  3. Open gINT
  4. Go to File > System Properties, Data Entry tab.  Ensure European Numeric Format during Data Entry is unchecked
