• The 64-bit version is installed by default unless a 32-bit version of Office is already detected on the PC
• If you do not see an install option after signing in, a license may not be assigned to your account - contact Twilight I.T. for assistance
• A slow internet connection, firewall, or antivirus software can make the installation take longer than expected
