After fighting a night and a day I now have readycache installed again. You need this expresscache version: http://answers.microsoft.com/en-us/windows/forum/windows_10-win_upgrade/sobre-o-expresscache-do-notebook-asus-vivobook/0519b546-a00f-42ae-b809-d8931637beb7?auth=1
Expresscache_Win10_x64.rar
It ended up with the message that I already had a newer version installed.
Then, when it decompresses it says it produces a file called expresscache.msi.
This file can be found somewhere around %LOCALAPPDATA%\Temp{E1E38DF6-5231-4B7C-B798-0708709777BC}. In any case it must be a new directory in this Temp-directory.
If you then start this msi with
cd %LOCALAPPDATA%\Temp{E1E38DF6-5231-4B7C-B798-0708709777BC}
msiexec /i expresscache.msi /Lv* output.txt
You can watch in the log in output.txt whatever remnant is obstructing the install. I succesfully forcefully removed the found GUID with a trial of Revo uninstaller pro 3.1.4.
Now let’s see whether this thing will let itself configure as I already tried the primocache trial on the 32 GB SSD, so it has to be manually reconfigured…
