Issue Details

When I try to open the TestStand program, I get the following error message:

Unexpected error reading the sequence editor layout configuration file:

Rename the configuration file so you will get the default layout next time you start the sequence editor?

How can I fix this problem to run TestStand program normally?


This issue can be resolved by the following steps:

1. Click the OK button in the prompt box to rename the configuration file;
2. If the first step cannot fix this issue, you can browse to the location of the layout_default_large.bin;
3. Replace the .bin file with the same file from another computer.

If none of the above methods solve the problem, please try to uninstall the TestStand and delete relative files in this locations. Reinstall the TestStand after that.
