Issue: Nothing happens when I try to open a TestFit file

When trying to open a TestFit file by going through TestFit. Open, nothing happens.


Nothing happens when you try to open a file.


This happens when trying to open a file which was created by a later version of TestFit.

This can also happen if the file type gets deleted. Verify the file type says "TestFit document" in Finder or "TestFit data file" in Windows Explorer.


If it says "document", edit the name, and add .rsd to convert it to a TestFit file.


Download and install the latest version for TestFit from the download section of our website.

If you still cannot open the file, please reach out to
