How to install without admin privileges?

Is it possible to install Sumatra as a user with no admin privileges on a Win10 machine?

When I clicked on the installer I get a dialogue asking me for the admin password.

Is this the only option?

Thanks

You can download portable version, place it anywhere on the disk and create a shortcut. There’s not much difference.

The installer needs admin permission only because by default we install to Program Files directory and writing there requires admin permissions.

no it doesn’t work

Default install to %localappdata%\SumatraPDF\SumatraPDF.exe is for single user install

For multiple users OR multiple UAC then I recommend the administrator should change options and install to common shared
Program Files\SumatraPDF\SumatraPDF.exe
The adminisitrative user should move the desktop shortcut to C:\Users\Public\Desktop and let everyone have that same access.

Each UAC account should automatically create its own %localappdata%\SumatraPDF\SumatraPDF-settings.txt

Does the installer never install to \Program Files folder?

I just installed on a new PC (win10) and the installer defaults to C:\Users\Username\AppData\Local\SumatraPDF

On my older PC it is C:\Program Files (I don’t remember if that was the default or I changed it).

If not already supported, can an “install for all users” option be added, please? That is the common standard and the “only for this user” default is a bit “out of the ordinary”.

Until then, with version 3.2 (64 bit), if I change the install folder C:\Program Files\SumatraPDF, will that properly install for all users or are there more steps needed? (besides the mentioned desktop shortcut)

Regards,
David

PS: To clarify, I am installing with an administrative user.

I have used and liked SumatraPDF in the past - today I tried to install it, it asked for admin login creds (perfectly normal), and said it installed. However, it wouldn’t work for the user account I actually work in, and despite installing it from said account, it would not let me uninstall the program. the integration for Windows 10 definitely seem to need some work on the newest stable version. I never ran into this trouble in windows 7 or 8.1 though I think I likely used admin-level users when installing it.

The old default was for any user to install to
Program Files or Program Files (x86) with user data in several places so that could cause some issues.of its own.
Rightly or not the developer has defaulted that each user may equally install their own copy which by default starts in %localappdata% the problem is that when installing users may alter the mix such that using elevated options may need a more elevated install than a basic user hence the name of this thread

My recommendation for install is use the common c:\Program Files for multiple user accounts, then each user will find their personal settings in their own %localappdata%. This may mean they need to relocate any historic preferences by copying/moving SumatraPDF-settings.txt to their personal folder.
