1Password for Windows App fails to launch

rkdinesh

Team,

I am a new user to 1Password, and installed "1Password for Windows" on my laptop running on Windows 7 SP1 64-bit. Problem is: I'm unable to open 1Password application, tried re-installing couple of times but no luck. Error message as per the Windows event viewer says "Application: 1Password.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception."
"Faulting module name: KERNELBASE.dll, version: 6.1.7601.24408, time stamp: 0x5c92f101".

I tried the solution documented in couple of forums (1) Check/Restart the Windows services i.e. Network Location Awareness and Background Intelligent Transfer Service (2) Uninstalled 1Password X Mozilla extension and re-attempted installation of 1Password app, both of them didn't worked out for me.

Any other suggestions please?.

Hello, @rkdinesh! I'd bet you've got an older version of the .NET framework on this PC. 1Password needs at least .NET 4.6.2 and, unlike Windows 10, Windows 7, 8, and 8.1 don't come with a new enough version of .NET. Try installing .NET 4.7.2 from here. Once you've done so, uninstall 1Password from Control Panel, then give installing 1Password 7 another go. Let me know if that gets things up and running for you. 🙂
