DLL not a valid Windows Image

[colin mcfaul]

I've got a VI ramping a voltage supply, and taking data from an oscilliscope. The actual communication between with the devices takes place via DLL library function calls.

When I load the VI, the relevant sub-VIs try to load the libraries. LV can't find the libraries, and pulls up a dialog box for me to find them. When I select the library that the VI needs, it returns something like: "tktds7k_32.dll File not found. Please verify the correct file name was given." The directory that appears to have the libraries I'm looking for contains several .mnu files. When I try to choose one of those, I get something like: "The application or DLL [...]\tktds7k_32.mnu is not a valid Windows image. Please check this against your installation diskette."


I've run this VI on three different machines. It works just fine on two of them; it gives me the error described above on the third. All three machines are running Windows XP. My best guess at this point is that the problem is with the OS. My interpretation of the error message is that XP can't read .mnu files. Does it even make sense that this would be the case? I don't know enough about XP to know if this in fact is the problem, or how to go about fixing it if it is.

If this is not the problem, is there anything else it could be?

Hi Colin,

What driver are you using to communicate with the oscilloscope? Is it an IVI-driver, and did you download it from our instrument driver website? If yes, reinstall the driver and see if that helps. If not, refer to this link for an alternative solution.

Hope this helps.

Turns out it wasn't the driver. Very straightforward user malfunction. There was a DLL file that hadn't been moved to that machine. I expected it to be easier to find, so I didn't look for it hard enough.

Thanks for the suggestion.
