I work day to day with a non-administrator account. When needed, I'll run programs as an administrator. This breaks with the latest Fiddler installer.

Steps to reproduce:

* Run setup for Fiddler 4.6.20171.26113 as a non-administrator

* When prompted, provide elevated credentials.

* Complete installation, and observe that you can use Fiddler as your non-admin user.

* Upgrade to the latest Fiddler from the upgrade dialog.

* When prompted, provide elevated credentials.

* Complete update, and observe that Fiddler is no longer installed for or accessible by your non-admin user.

* Try to install the latest Fiddler from the website download.

* Decline elevation (so it will install for your user)

* Observe that installer fails to run.

* Try again, but provide elevated credentials

* Observe Fiddler is not installed for or accessible by your user, but instead, for the admin user.

* Roll back to Fiddler 4.6.20171.26113 where everything works like it should.
