Trying to deactivate trados license but getting error: multiple instances of this application running

Question

I'm trying to deactivate my trados license to change to a new desktop computer and I keep getting this error: There are multiple instances of this application running . Close the other instances before before deactivating the license. 
 I have restarted windows multiple times and it's still not working. Note I am working on a mac via a virtual machine (parallels desktop) 
 Please can you let me know what to do as I need to work asap. 
 Thank you
