Hello... Downloaded and installed v8340 in trial mode that expires on 4/18/19 on Windows 10 v1809 w/all current updates. When attempting to upgrade to v8341, v8342, or v8343 I get a file corrupted error (pic attached) and asks me to run a virus scan and reinstall the program. Running Windows Defender yields no viruses on any of the files. I've tried to uninstall/reinstall and exclude all the offending versions with the same results. Any ideas? Thanks for any help or suggestions...
