After unzipping change the extension in .exe (not necessary in case the zip file is password protected). As DiAna is a "portable" application you can save it anywhere on you disk and run it. Probably Microsoft Security Essential of Bitdefender will give a virus warning. It's a 'false positive', so disable this virus scanner or add an exception for this program. As there is not yet a manual, please read the discussions on diyaudio.com and/or hints on my website. Note: After installing a new version, delete the ini file of the previous version! Under Windows 10 run this program as administrator, otherwise you will get a stupid warning. In case of an RTX6001 sound interface, don't run the RTX Attenuation Control utility at the same time. Good luck.
