Hi,

Please make sure the LabVIEW run time engine of which the instrument was created is installed

Let me know if you have other questions.

sir,

what is the particular NI LabView run-time engine version? On the national instrument software(product tab) I have two(2) NI LabView Run-Time Engine 7.0 & NI LabView Run-Time Engine 7.1.1

Do I have to remove the two(2) old version?

thanks!

Hi,

Go to the LabVIEW instruments installation folder under program files on your computer. For instance, if you use Multisim 11, it will be:

C:\Program Files\National Instruments\Circuit Design Suite 11.0\lvinstruments

Right click the microphone instrument LLB file and check which version of LabVIEW it is created with, this is the version of the LabVIEW RTE you should install.

If it still doesn't work, please check this article on how to properly install LabVIEW instruments

In Multisim, go to File>Open Sample and select the microphone and speaker design under the LabVIEW instruments folder.

This is a working designn, you can use it a s a starting point to troubleshoot your mic and speakers.
