Get App Installer
Winget ships inside Microsoft App Installer on supported Windows 10 and Windows 11 builds. Install or update App Installer from the Microsoft Store, then reopen PowerShell or Windows Terminal.
Check winget
Run winget --version. If the command is missing, finish App Installer setup and open a new terminal window.
Install SumatraPDF
winget install -e --id SumatraPDF.SumatraPDFThat id is the pdf reader install path mapped here. Longer guide: winget install, Windows install.
If winget is blocked
Take SumatraPDF-*-64-install.exe from the project download page instead. Chooser: install.exe or winget. Safety: download safe.
Quiet Windows checklist
Confirm App Installer from Microsoft when the package manager command is missing. Reopen Terminal after App Installer lands, then retry the documented line. Checksums, when published, live next to assets on the official download page. Read COPYING on the project site before you redistribute a modified build under GPL terms.
Keep the first pass short. Open a disposable document, Find once, and confirm the page canvas. Prefer the same update door later so Start Menu shortcuts stay honest after upgrades.
Licence and update habits
Upstream licence text is GPL-3.0 on the official site. Winget locale language matches that free software story for the desktop Windows build. Prefer one install door per PC.
When fleet policy wants a manual install.exe, take it from the same official download page winget already wraps. Stop if a page asks you to disable SmartScreen for an unknown publisher before the official package arrives.
When something fails
If SumatraPDF is missing from Start, confirm the setup finished and avoid downloading a second renamed installer. If Find looks wrong, reopen the document rather than stacking mirrors. Safety and first-run guides deepen those checks without inventing competitor prices.
Related routes cover releases, GitHub source overview, download-safe habits, for-this-computer mapping, and vs Adobe Reader. Home keeps the Windows install command with a Copy control.

Return to the sumatrapdfreader.org download page or the documented winget identifier instead of stacking repair utilities. Catalog versions can lag a day behind a fresh official upload. Public copy still says the current release rather than freezing a screenshot number.
Repair without mirrors 1

Related routes cover releases, GitHub source overview, download-safe habits, for-this-computer mapping, and vs Adobe Reader. Home keeps the Windows install command with a Copy control. Prefer the project download page for SumatraPDF-*-64-install.exe naming and skip Softonic-style wrappers that rename the file.
Sample then deepen
After a clean install, open one short trusted document before you touch personal archives. Turn a few pages, try Find once, and confirm Recent or File Open still lands on the same path. Large scanned archives can wait until that first hour looks calm.
Portable zip, 32-bit, and ARM64 packages stay supporting mentions only in this Windows x64 install map. Take those from the same official download page when your machine needs them. Keep using winget upgrade or a newer install.exe from the same door for the next update.
