yes, I tried and found I cannot download weather file on the Location and Resource page in PVWatts case. The Error information showed "Download error, Failed to convert to latitude-longitude pair:"15013 Denver West Parkway, Golden CO 80401". BTW, this location information is from HELP example and I tried all location information with different type but the same error.
The welcome page is by starting sam.exe('.../'sam_dev/sam/deploy/x64/).
Thank you Paul for you patient response, truly grateful.
