So you copied the contents of the .zip archive to the root of your Kobo. Does that mean you copied the .adds and .kobo directories from the archive to the root of your Kobo's exposed storage?
The One Click Install script for Windows PowerScript does show a series of steps that you must follow. So to basically recap the Windows method shown in
message #2 in this thread
[list=1][*]You downloaded the OCP-KOReader-v2025.04.zip file and placed it in a directory on your Windows computer.[*]You downloaded the installer script (install.ps1) and copied install.ps1 into the same directory as the .zip file(s) you downloaded.[*]You unblocked the installer script as per step 3 in the instructions with pretty pictures.[*]You ran the installer script either by right clicking and
run with Powershell or by opening a Powershell command window, CDing to the directory where you placed the files and running .\install.ps1 (the .\ or ./ is required since by default, Powershell does not look in the current directory). This is my recommended method since it allows you to see any error messages.[*]Once the install was finished, you safely ejected your Kobo, watched the install screen run and your Kobo rebooting and coming back to the GUI.
Image of running ./install.ps1 in the same directory as two OCP packages is attached.
Manually installing the package is a lot more pain since you need to modify the ExcludeSyncFolders line under the [FeatureSettings] header.
Code:
[FeatureSettings]
ExcludeSyncFolders=(\\.(?!kobo|adobe).+|([^.][^/]*/)+\\..+)|(screensaver_old)
IgnoreCaptivePortal=true
InvertScreen=false
Screenshots=false
