What does it install?
Section titled “What does it install?”Presto-Setup.exe extracts the Presto Desktop application files into the user’s local app data directory and (optionally) creates Start Menu shortcuts, a Desktop shortcut, an Add/Remove Programs entry, and an auto-start-at-login registry value. The main application is Presto.exe — documented separately at What is Presto.exe?.
All of these side effects are optional and can be suppressed via installer flags for fleet deployments. See IT Deployment for the full flag reference.
Where does it install?
Section titled “Where does it install?”%LOCALAPPDATA%\Presto\This is a per-user installation. No administrator privileges, UAC prompts, or elevation are required. The installer does not write to Program Files, HKEY_LOCAL_MACHINE, or anywhere else that would require elevation.
Is it safe?
Section titled “Is it safe?”Presto-Setup.exe is signed with a DigiCert Extended Validation (EV) code signing certificate, the highest level of publisher identity assurance Windows recognizes. The signature is timestamped to remain valid beyond certificate expiry.
- Windows SmartScreen recognizes the EV signature and does not display “unknown publisher” warnings
- The installer downloads no additional code at install time — all files are bundled inside
