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.
The work arround is, to install it as admin user in a folder accessable for the non admin account. But this is a very annoying bug.
