When to use winget
Use winget when App Installer already works and you want the catalog package id SumatraPDF.SumatraPDF.
When to use install.exe
Use the manual SumatraPDF-*-64-install.exe when winget is blocked, or when you prefer the project download page directly.
Portable zip
A portable zip on the same download page is supporting. It is useful for USB runs. It is not the default install mapping on these Windows notes.
Quiet checklist
Confirm App Installer or plan the official install.exe door first. Keep one sample PDF open in a folder you control. Prefer the same update door later so shortcuts stay honest. Skip Softonic-style wrappers that rename the install.exe before the official file arrives.
Editorial stamps inject the live release tag from the build feed when present. Body copy still says the current release rather than freezing a screenshot number. Licence text stays on the project COPYING for SumatraPDF.
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 so Start Menu shortcuts stay honest after upgrades.
When App Installer is missing, install it from Microsoft, reopen Terminal, and retry the documented command. 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. Return to the sumatrapdfreader.org download page or the documented winget identifier instead of stacking repair utilities.
Sample then deepen
Keep the first pdf reader pass short. Open a disposable PDF, Find once, and confirm the page canvas. Change tabs only when you need a second document. Large archives can wait until one Find looks right.
Related cluster pages 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.
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 PDF rather than stacking mirrors. Safety and first-run guides deepen those checks without inventing competitor prices.
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.
