Ladies and gents, We use MathCAD 15 in our office and we have an excel component in a mathcad sheet that works fine for some people but when some users open the sheet they get the following message - 'Warning: an unrecoverable read error has occurred. 1 regions could not be read from this document.' the excel component is then deleted.

There are only 24 inputs (that have 8 values within them) to the excel component, so its not even that large. We are all operating on the latest MathCAD 15 release for windows 10.

Any ideas?

So what are the differences?

Version and/or bitness of the OS (are all using Windows 10, 64 bit?)

Version of installed Excel?

Good question,

Both systems are running windows 10 and excel 32bit, hence the confusion as to why we have an issue.

So I understand that the effect on the two machines is reproducible.

Both use the same file (from the very same network share or the same thumbdrive) and one machine always will throw the error and the other will always load the file without problems?

If the file is not taken from the same source by the two machines, one copy may be damaged.

The same file on two identical configurations - thats confusing. So I guess there must be something which makes a difference.

I fear that I can't be of much help here as I am just poking around. My next try would be to delete the Excel component and load the new file on both machines. I would suppose the file will load fine on both.

Then I would recreate the Excel component from scratch and see if the problem persists.

The last time I can remember I stumbled over this very same error message was with Mathcad 14. It usually happened with very large files (containing a lot of inserted pictures) and the usual cure was to identify and delete the faulty region (using Stuarts repair sheet) to be able to recover most of the rest of the sheet. But your case is different as the sheet works fine on one of the machines you use.
