You can use this as a guide to finding your way around even though you are deleting rather than backing up - Use InstallUSB Notepad as a rudimentary File explorer to backup files - TenForums Or boot from, for example, a Windows 10 InstallUSB and use its command prompt to delete the folder without having to alter any permissions. The PC has an Intel( R) Core( TM) i5-8400 CPU 2.80GHz 2.81 GHz & 32GB of RAM. If I right-click on the files and open Properties > Security I can't find any way to change the owner of the file to me (I am the administrator).ĭoes anyone know how to delete these files? If I try to delete these manually I get a message that says "You require permission from SYSTEM to make changes to these files". I have scoured the registry and hard drive and the only thing I can find relating to Reader are two files located here: C:\Program Files (x86)\Adobe\Acrobat Reader DC\Resource\CMap The files are called Identity-H and Identity-V. At this point installation stops and all the new installation is deleted from the hard drive. Double-clicking the installer starts the installation process and all goes well until the installation is almost finished and then I get a message to say that a newer version is already installed.

I go to the Adobe web site and download the installer.

A while back I accidentally deleted Adobe Acrobat Reader DC from my PC and I need to reinstall it.
