Installation Does Not Progress Beyond 21%

During Endpoint Encryption Deployment Tool installation, the installation stops at 21%. Even after canceling and restarting installation, the progress bar does not pass 21%.


This issue may occur because Microsoft .NET Framework 3.5 is not installed or enabled on the OfficeScan Server endpoint.

Install .NET Framework 3.5 manually or enable .NET Framework 3.5 in Windows Features.
