Example of problematic file:  Model050913.mw

Maple 2020 (either 32- or 64-bit), Maple 2019, and Maple 2017 cannot open a .mw file that I created in 2006.  These Maple versions display this .mw file from 2006 as a garbled mess and cannot work with the garbled mess.  In contrast, Maple 18 opens this file from 2006 without problems.  Did the .mw file format change some time after Maple 18?  Interestingly, Maple 2020 can open a .mw version of the problematic 2006 file that I save with Maple 18.  Can Maple 2020 be updated so that Maple 2020 can open old .mw files (e.g., 2006 and earlier)?  Is the inability of Maple 2020 to open files from 2006 and earlier a bug in Maple 2020?  I can workaround this problem by using Maple 18.  But correcting a bug in Maple 2020 that garbles old .mw files would be helpful.

What is the solution to this error message when trying to run the Maple add-in for Excel?
"The specified module could not be found.  OpenMaple cannot find Maple engine library, maple.dll."

I am running Maple 19.1 and Excel 2016, both 32-bit, in Windows 7.  Excel appears to have successfully installed the Maple add-in.  For example, the Maple add-in icons appear on the Add-ins tab of Excel.  Excel shows the Maple add-in as active in the list of add-ins.  The location of he WMIMPLEX.xla is correct at "C:\Program Files (x86)\Maple\Excel\WMIMPLEX.xla.

Maple support tells me that Maple should add its "bin" folder to the PATH key for excel.exe in the registry key "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\excel.exe\Path".  This path information, however, is not in my computer's registry.  This missing path information might be an obvious problem.  But what is the correct registry entry so that Excel knows where to find the Maple engine library maple.dll?

I tried adding the path to maple.dll in the environmental path variables of Windows 7, but that approach did not work.  I have uninstalled, rebooted, and reinstalled Maple 2019 (32-bit) several times.  Still the same error message.


My attempt to export array data using the Browse>Export option when looking at the data fails to work as needed.

The exported data always start in cell A1 of the Excel worksheet even a different starting cell is entered into the Matrix Browser export window.

In summary, my experience is that the Matrix Browser matrix export in Maple 16 and Maple 17 ignores the information about the intended starting destination cell in the Excel file.

Does anyone find that the Matrix Browser exports to a starting Microsoft Excel cell other than A1? 

This exporting with Matrix Browser worked find in Maple 15.  It has been broken in Maple 16 and 17, including Maple 17.02.
