Cannot open simulink .slx file

I cannot open my simulink file after adding tags to it. I think the problem is using the File Meta Association Manager to create Tag property for .slx file. I also cannot delete the tags now. Can someone tell me how to recover this simulink file please?

Can you attach the file here for us to test?

Sure, thank you very much.

It loads for me, but seems ot be missing a library commhdlio which appears to deal with HDL; I do not have all of the HDL installed.

The model was saved with R2018a. Is it possible that you are using a release earlier than that?

[debing wei]

No, I am using 2018a

If you can open it, could you save it as a different name and attach it here please. I wanna try and see if I still have the same problem. Thank you very much.

I do not appear to have the comhdlio library installed in any release, so I am having difficulty tracking it down. I am also having difficulty finding a source for the model that might document requirements.

This issue could be related to the file structure while saving which may be getting corrupted. This has been reported as a bug for this release.

Possible workarounds:

(1) Copy and paste entire contents of the main model from the old one to a new one and save that as SLX format.

(2) Save the original file in MDL format first, using "Save As" and re-save in SLX format. Although this is a convoluted method, re-saving the final SLX format as SLX again does not lead to the error later.

Hi Munish,

Thank you for the advice. I still get a little bit confused here. Since I cannot open the model, how can I copy the entire contents or save it in MDL format?

[Walter Roberson]

If you can post the link to the complete project, I might be able to do the conversion, as it opens for me.
