Drop-Down Boxes Not Working?

[ptc-4598893]

Hey, I hope this is a quick and easy question. Searching online hasn't gotten me anywere.

I work IT at a University and one of the students using MathCad has a complicated script from a former grad student which uses scripts and drop-down selection boxes. When loadin the file on his personal machine, the drop-down boxes don't work (no items in them). When loaded on our shared power-horse machine, though (through remote desktop), the menus work fine. He also gets Internal Errors frequently for tasks such as editing plot properties.

What could be different about his machine that I should look at, and would a re-install with full options fix it?

Thanks,

Eric

Sorry, but it is very common question.

What kind of PC, OS, Mathcad etc You have?

[ptc-4598893]

Hey, good questions. This is MathCad 15, Windows 7 (SP1) and a custom-built PC.

Make sure he has all the prerequisites installed on his computer. They are in Read This First.

They are:

.Net 3.5 SP1

MSXML 4.0 SP2

MDAC 2.8

He also run Mathcad 15 as an administrator.

Hey Mona,

Thank you for your comment, he is current on all of those (.NET 4 comes with W7) and the problem happens whether or not this is an Administrator account. FYI we use Mathcad 15 fine on non-admin accounts (other machines). Is there anything else you could suggest?

Thanks,

Eric

Do you have graphics hardware acceleration turned on? If so, try turning it off. It sounds as if a component may be giving the problem, so I'd try updating the graphics drivers, then doing a Repair (from Add or Remove Programs in control panel) before resorting uninstall and re-install.

Eric,

Can you see what the scripts were done with? People program scripts in Mathcad 15 with Visual Basic, VBScript, and JScript. It sounds to me like there's something missing involving one of these programs on his machine.

Take a look at the Developer's Reference under the Help menu.

Perhaps technical support can provide some suggestions, or another user who uses scripting.

I have had occassions where scriptable objects stop working because they have become unregistered for no obvious reason.

Search for "mcmreg" in the Developer's Reference help file. You may need to register the component again.

I stumbled across the solution to this while looking form something else in the Help files.

For some unknown reason, the components (.mcm files for text box, list box, and so on) were not "registered" in MC15 when it installed, although they were in the Mathcad folder.

The problem is solved by finding "mcmreg.exe" and opening it. A dialog box appears showing various folders. You then navigate to the folder where the .mcm files are located (typically C:\Program Files\Mathcad\Mathcad 15\mcm) and select all the .mcm files and click open. Another dialog will appear indicating that all the files were registed.

That's it.
