Can't create a virtual domain (3 replies)

I have created many virtual domains in the past with wampserver, but now everytime i go to the Add a VirtualHost panel and paste in the complete absolute path to the virtualHost and the name of the virtual Host and click “Start the creation of the virtualHost” button I get the error message
c:/users/edkna/onedrive/documents/mysites/site1 does not exist or is not a directory. the directory does exist and i was careful to put the correct path to it.
any ideas why I am getting this message?

thanks!
