I downloaded Sweet Home 4.6 last night and couldn't get it to run, no error message or anything, just didn't do anything. Thought I had gotten a glitch in the download so deleted it this evening and downloaded again. Now I get the message

"Unable to execute file: ...SweetHome3D.exe

CreateProcess failed; code 740
The requested operation requires elevation."

Please decipher in plain language.
(I already deleted the previous version I had installed [:((]
