By default, both Firefox and Chrome installer will attempt to elevate and get the program installed system-widely but in a lot of cases, you may prefer only having it installed only under your own user profile, especially on a system that doesn’t have both browsers installed.
It’s really easy to do, if you know the trick. All you need to do is to decline the UAC when prompt so that both of the installers can continue on without the local admin privileges.
After launching Chrome installer, say No to User Account Control when prompted.
Then click Yes to the dialog box that pops up asking if you want to continue without administrator privileges.
The browser will be installed in the local profile at the following location so it won’t interference with other users on the same computer.
The same process applies to Firefox as well. After saying No to User Account Control when prompted, the installation continues on installing the program in the current local user profile.
If you are already part of the local admin group, you can still do the same to install Chrome only in your account but won’t be able to do the same with Firefox. The Firefox installer simply gets terminated when answered No to the UAC.
