Took a quick look because some ByteScout apps are portable -- this one isn't. Google & you'll find a ton of apps & web sites that'll generate a QR code for you, or you can go with this Chrome extension: chrome.google[.]com/webstore/detail/qr-code-generator/afpbjjgbdimpioenaedcjgkaigggcdpp?hl=en-US
There are 32=bit & 64-bitr versions of QR Code Generator 1.0.0, and with the exception of printing, it does work. Installation is a bit odd, with the program's folder in C:|Users\ [UserName]\ AppData\ Local\ Programs\ [If you select the default install for only me during setup]. You can however move that folder wherever you'd like. The app's configuration files are in C:|Users\ [UserName]\ AppData\ Roaming\ , and if those files are not there, when you run the app it'll add them. The registry gets a weird key -- [HKCU\ Software\ e159f80a-88bd-5010-ace3-9a4d9c2afcaf] -- plus a key for uninstall.
