Unresolved Symbol error while executing interactive virtual instrument

[Patrick.ASE30]

Hello everyone,

I develop an application for several customers, on a PC running under Windows7 32 bits and CVI 2013. On this computer are installed DAQMX V.15, IVI V.14, VISA V.15, one PCI-GPIB board and one PCI-6515 board.

I need to use several instruments (scope, power supply, DMM), and firstly wanted to try using the interactive execution mode as I already did several years ago (CVI 6...).

So I installed the driver instruments found on NI website (for example about the TBS1052, I installed the following driver "tktds1k2k_setup.exe" found here : http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=22950), but for any of them, there is an error when I try to acces to the first function (Init). It indicates "1, 1 error: Unresolved symbol: _Ag34970_init@16" or similar depending on the instrument. It's similar for every instruments I tried, even if its on a GPIB, LAN, or USB physical link.

The instruments I tried are (Agilent 34970a, Scope Agilent DSO x2002, Power supply Tdk Lambda GEN 150-16, Scope TBS1052). 

On the other hand, I tried to acces those instruments with NI MAX, and here it's OK, there is no problem to communicate. So, the physical links are Ok.

Do you have an idea about this problem ?

Maybe in the way I installed the driver, of a compatibility problem.... other ?

Thank you in advace for your help,

Have a nice day.

Hello Patrick,

You can try checking "Include project files in Interactive window" and "Include loaded instrument drivers in Interactive window" checkboxes in Environment settins(Options>>Environment). Make sure that the instrument driver is loaded(i.e. it appears in library tree).

Also check in target settings(Build>>Target Settings) that "Enable LoadExternalModule" is checked.
