Default LtSpice missing components error?

Hi, I have just installed LtSpice and did try to open an example file. When LtSpice do open the file, I get this error and when in a new or loaded file, I can't get the program to make the symbols.


Can anyone please give some advice?

In the Control Center, check the paths to the symbol and lib folders.
Obviously, LTspice can't find it where it thinks it is.

Do you mean like on this image?


LTspice has no problem finding inductors or resistors, even that they are not written in that list.

Post the .asc file you have initially loaded into LTSpice.

P.S.
Do have this path?
Path: "C:\Program Files\LTC\LTspiceXVII\lib\sym"

You must have voltage.asy, diode.asy and cap.asy files in the sym directory.

The file I am trying to use, is one of the files in the example folder: C:\Program Files\LTC\LTspiceXVII\examples\Educational\Pierce. asc


But even without trying to load that file, I can't use the three component types in a new file.

This means, either the files are missing or misplaced. Look into the 'sym' directory to verify whether the files are there.

The path is shown in my previous post.

Yes sorry, but yes the 1KB files are all there, what I do not understand is that all the other components work and is placed in the same folder.

It is very strange that Pierce.asc can not find cap.asy, voltage.asy and diode.asy, even though the files exist in the sym directory.

Do these symbols appear in the Select Component Symbol dialogue box? If you try to place one of these components on a schematic, can LTspice find the correct files?

I think as a first step you should uninstall LTspice and do a fresh reinstall.

Yes it's wary strange, I'll uninstall it all and try again! :-)
Here is how the error behaves:
If I stat it up and select new file, no error at all but non of the three components are beeng showed if I select one of them from EDIT or the component list, but at no time do I get any errors at all.
If I chose to open a file, then do I get the error, seen in first post.

I have now tried several things, uninstall, and reinstall, find other mirrors, even tried an older version. I think that somewhere in the leftover from the first install lies the problem.


Do any of you know a place to maybe get a real old version, I then can upgrade?
