I have downloaded a Rescue disk based on Win10 PE x64. It's downloaded from https://www.hirensbootcd.org/download/ I have rebuilt the ISO and have included a new folder with some additional apps like Textpad (and a few more) that I plan to just install on X: RAM Drive for that current session when WinPE Rescue disk boots.
This is just an isolated folder and contents are not integrated into WIM file in anyway. Since it resides on DVD, I can simply access it by accessing DVD Drive Letter in Windows Explorer when WinPE loads.
In principle this is fine, and some apps (like Minitool Partition Wizard) do install fine and run from X: RAM Drive as intended in WinPE Environment.
However apps like Textpad (5.4.2 x64)refuse to install in Live WinPE stating following error.
The system administrator has set policies to prevent this installation.
The title bar of the message box says Windows Installer. I guess the issue is with the built-in SYSTEM account.
I tried right click the exe and run as admin but that did not help.
Is there any way I can install apps like Textpad in Win10 PE (say on RAM Drive) for that session? To my best knowledge there are no user accounts in Win10 PE. Even the User Accounts option in Control Panel does not open.
