1Password for Windows is tested in these operating systems:
- Windows 7
- Windows XP
Customers have reported success using 1Password in Windows Vista.
Note: The 1Password installer requires “admin” rights to complete the installation, and you may need to restart Windows after installation is complete. (You don’t need to be logged into an account with “admin” rights to use 1Password, though.)
The 1Password extensions are tested for compatibility with only the current “stable” (non-Beta) versions of these web browsers:
- 32-bit Internet Explorer
- 32-bit Firefox
1Password may continue to work with older versions of these browsers, as well.
