Question

How to install yarn on Windows 7 as non-administrator?

Yarn documentation mentions three installation methods for Windows: .msi installer, Chocolatey and Scoop.

• .msi installer requires administrator rights even if setting installation path to %LocalAppData%\yarn.
• Running choco install yarn on a non-administrative Chocolatey installation fails with a 1603 error code when executing C:\WINDOWS\System32\msiexec.exe. The ỳarn.MsiInstall.log contains the following error: Product: Yarn -- Error 1925. You do not have sufficient privileges to complete this installation for all users of the machine. Log on as administrator and then retry this installation. The chocolateyinstall.ps1 contains a command which is called Start-ChocolateyProcessAsAdmin and I don't see any flag. So I don't think that will work at all.
• Scoop requires Powershell >= 3 but it's PowerShell 2 on my Windows 7 machine.

Installing via npm install -g yarn works but is not recommended.

Well, the releases page for Yarn on Github contain .tar.gz archives, e.g. https://github.com/yarnpkg/yarn/releases/download/v1.7.0/yarn-v1.7.0.tar.gz which does work on my Windows 7 (x64).
