DLL multi instance issue

[Nacho_47]

Hi all & thanks in advance.

I´m trying to load DLLs generated by CVI that it´s calling dinamically/statically(i tryed both) to a DLL.

I call 3 times to different DLLs thats it´s calling to same instrument Dll. when i try run, a Pop-up message return. The problem it´s if i try to run and locate this DLLs on EXE developed by CVI at the same time . Works fine without any problem. So why it´s ocurring this on Test stand?

The DLL for sure it´s fine, due to it´s working on the EXE...

So once i try to run Test stand, the message that shows it's:

Could not load DLL or external library 'C:\NACHO\DLLS\PSA_Driver_CAN_Vector_N1.dll'.

This DLL requires the following DLLs which could not be found or loaded:

Hi, I got into the same issue for a different .dll file.

Did you find a solution ?

[Nacho_47]

Hi, nothing new.

Just note,at least under my experience, with Teststand 2010 you cannot instantiate just only one time this dll, more than 1 make error. In case you use est stand 2017 you can instantiate up to 2 dll, more than 2 you find error.

The final solution was make 1 DLL+ 1 Exe(socket client + socket server), you instantiate on test stand the Client(dummy dll only run at strart the Exe & send parameters)  to the server, where  you instantiate the Original DLL.

By this way you can instantiate N times the DLL under conflict.
