Regional Checkpoint

I suggest you create a new project, and then try out Regions. If you haven't done so already, follow the documentation https://support.smartbear.com/testcomplete/docs/testing-with/checkpoints/regions/about.html, https://support.smartbear.com/testcomplete/docs/testing-with/checkpoints/stores/regions/about.html, https://support.smartbear.com/testcomplete/docs/reference/project-objects/items/stores/region/index.html, https://support.smartbear.com/testcomplete/docs/reference/project-objects/items/stores/regions/index.html. 

 

As the log message states "The size of the images is different" image comparison is tricky if your image is changing all the time https://support.smartbear.com/testcomplete/docs/testing-with/checkpoints/regions/factors-affecting-image-comparison.html 

In the log, you are viewing the Details tab, click on the Picture tab to see the images difference. When you create the region checkpoint you can adjust the tolerance Checkpoint Wizard - Specifying Comparison Parameters (Region Checkpoints) | TestComplete Documentation

It may or may not apply here but you can parameterize your region check points...

There are other image comparison options available in TestComplete...

Using region checkpoints is not the only way to verify that an onscreen object in your application under test is displayed correctly. You can create a test that will obtain the image of the desired object and compare it against the baseline image using the following alternative approaches:

Use the Compare Pictures Operation and the Regions.Compare Scripting Method

Use the Picture.Compare and Picture.Difference Scripting Methods

Create a Custom Comparison Procedure
