About Helium
Helium 1.0.0 is an interesting Android tool which allows you to create backups of your phone's data without the requirement of having your device rooted. Formerly known as Carbon Desktop, Helium creates backups of cell phone settings (like WiFi and User Dictionary), messaging (SMS and MMS) and your installed apps. One cool thing about the Helium application is that it can backup your data to both your hard drive and your Google Drive. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system/platform without restrictions. Helium is available to all software users as a free download for Windows.
Is Helium safe to download?We tested the file CarbonSetup.msi with 27 antivirus programs and it turned out 100% clean. It's good practice to test any downloads from the Internet with trustworthy antivirus software.
Does Helium work on my version of Windows?Older versions of Windows often have trouble running modern software and thus Helium may run into errors if you're running something like Windows XP. Conversely, much older software that hasn't been updated in years may run into errors while running on newer operating systems like Windows 10. You can always try running older programs in compatibility mode.
Officially supported operating systems include 32-bit and 64-bit versions of Windows 10, Windows 8 and Windows 7.
What versions of Helium are available?The current version of Helium is 1.0.0 and is the latest version since we last checked. This is the full offline installer setup file for PC. At the moment, only the latest version is available.
Helium 10 Chrome Extension
What type of graphical file formats are supported?Helium 10 X-ray
Helium supports over 3 common image formats including EPS, MPO and PLY.
