Alen,
I just checked on tr.graphisoftus.com and the library updater
(2284) can be used in the EDU version of AC 8.1 (some patches can't).
As I remember, this updater installs a complete new library
and leaves the existing library with the appendix "old" added to the name.
The AC 8.1 library has some folders called "classic....." which
contain 8.0 versions of some 8.1 library parts.
Sometimes these folders are overlooked.
You may be right that the tutorial was written for AC 8.0
You might also be right about the EDU library being stripped down.
I am sorry I can't verify this.
Perhaps someone else who has both versions can.
You might try copying the exact name of a part mentioned in the
tutorial and doing a "Find" for that name.
It sounds like this project was started in 8.0 and then opened
in AC 8.1 and the AC library 81.pla was added
and the 8.0 library was moved from the disk that AC
is looking in to find the libraries.
If you still have the 8.0 library, put it where AC can find it,
load it into the project via the library manager,
and remove the AC library 81.pla so you don't get
duplicate library parts error messages.
AC 8.1 can work with the 8.0 library and when you save
the project it will be updated to an AC 8.1 project.
This way you can use AC 8.1 rather than 8.0 which is full of bugs.
Thank you,
Peter Devlin
