Getting an Emulator Error Drivers Fails to Install

Hello there!
Can anyone help me out with my MSP430? I am getting an Emulator errors when I try to connect my board to the computer. I was working with my IAR embedded workbench for MSP430 and eZ430 – RF2500.
When I tried connecting to plug the target board to my computer, the driver fails to properly install. I tried updating my workbench and installed all the necessary programs.
However, whenever I download with my emulator an error window pops up.
I have a screenshot below of the error.
Fatel error: No communication dll found
Session adorted!
I desperately need help fixing this.
Thank you!
