Embedded Excel file issue in Mathcad 10
Hi guys,
I'm having issues with embedded Excel files.
After opening a Mathcad Prime 10 file with an embedded Excel file (from which I'm reading in data for calculation) MC suggests that I might be editing the Excel file and thus the calculation can't continue; see screen shot.
Has anybody experienced the same issue and (hopefully!) a solution to the problem?

Some more information:
- Win 11, 64 Bit machine.
- MathCad Prime 10
- Checked Task Manager for background Excel files running - none.
- I've deleted the Excel file and "re-embedded" a new one - same issue.
- New Mathcad file with new embedded Excel file - same result.
