Issue
During the installation process we are invited to enter a folder location for library storage. No matter the folder locaton we put here, we still have the same error message, “impossible to create library folder for you”.
We have granted all the rights to IIS_IUSRS to the folder we have created but still have this message.
Is there any particular requirement for the folder we have missed ?
