I am attempting to install Premier Elements 2018 (free whilst I choose whether to buy) and have encountered the issue that my installation is incomplete. When I click "error summary" I am told that "Your file was not found" (ERR_FILE_NOT_FOUND_).
I am unable to install and, therefore, unable to decide whether to buy. Also, without adequate support from Adobe, I am disinclined to buy.
AMD A10-5750M APU with Radeon Graphics running at 2.50GHz
I unzipped the downloaded file and attempted installation from Adobe Premiere Elements 2018>PRE 2018>Set-up.exe whereupon Adobe Installer opens for "Initializing." Then I get "Buy" or "Try". I hit " try", enter my Adobe ID and reach "Install". After about 20 minutes (this is my third attempt), I reach the messages that you have seen.
