Issue Details

When I open my VI or a subVI, I get the following error:
The VI has changed on disk since last saved or loaded by LabVIEW. 
If you load its front panel, it will probably be inconsistent with the parts of the VI already in memory, resulting in a corrupt VI. 

Solution

This error is most often caused when a third party application such as automatic backup software or antivirus opens up a VI and makes minor changes to its metadata, such as the timestamp.

To avoid this error, revert to the previous version of the VI and then make sure that the VI save location is omitted from any automatic software backups or updates. 

Additional Information

This error sometimes more likely to occur when a VI is saved on a network location and can be accessed by network security or management software. 

Always maintain a version control system on all LabVIEW code including making backup copies of important VIs in order to prevent loss int he case of corruption.
