Object Reference Error

Asked Oct 2012 — Edited Oct 2012

Hi every one, since I updated EZ builder, each time I start a project I get an error message saying unable to load. Reason: Object reference not set to an instance of an object. And some of the change made to the project no longer saved. For example I would put a camera device on the project, save it, but when I reopen the project it will not be there. Can someone please help?

Are you certain you are running the most recent version? There are no reports of something like that. Also ensure you have .Net 4 runtime installed and updated.

Thanks DJ, for your quick reply. Yes I'm using the latest version and since the error begun I manually installed .Net 4.5 runtime, checked windows update.

Interesting, there's always one in a thousand of windows installations that is troublesome. My suggestion is usually to ensure the updates, uninstall the software, reboot, reinstall software and cross your fingers

What operating system are you using?

I have done that DJ but the problem persist. I'm using windows 7 home premium. I'm going to use system restore to try saving the project at an earlier date, and also try to save the project on a different computer. I'll let you know what happened.

I can't imagine what the issue is. After you have uninstalled, can you look in the c:\Program Files (x86) folder and see if there is an EZ-Robot folder? If there is, can you remove those folders manually? Then reboot and re-install.

Thank you DJ for these instructions, I followed them but the problem persisted. I tried to save an earlier version of the project file from EZ cloud and it worked. There was no error! Conclusion: The project file got corrupted. Thanks DJ, for your help.
