Hi, 1722 is means RPC Service not available Please try to disable your network card and then try to install Exchange Load Generator. Besides, you can try the below steps.

I had this exact issues and Xiu's recommendations worked perfectly. I disabled the network card and the install finished in only a few seconds. Thanks.

For anyone who may find this from a search, disabling the NIC will allow successful installation of Loadgen, however if you plan on using the remote service it will not work. Create an entry for http://crl.microsoft.com to 127.0.0.1 in the hosts file before installation, the install will then work, as will the remote service :)
