Can't save library features

I did the following steps:

Close the sketch and do the following:

Click the Design Library tab to open the Task Pane.
Click *the pin* to pin down the Task Pane, and select Design Library .
Browse to folder where you want to add the library feature.
Press Ctrl and in the FeatureManager design tree, select the features you want to save as a library feature.

[Do not include the base feature as a part of the library feature. If you include the base feature, the base will be part of the library feature (*.sldlfp) when you drag it to a model.]

Hold down Ctrl, and drag the features to the lower panel of the Task Pane.

I also tried:

1. Click the Design Library tab

2. Click 'Add to Library'

3. Select the feature to add

4. Name the feature

5. Click the green check mark

Depending on which folder I choose to save the file in I either get this error:

'Failed to save file'

it appears to save, but there is no feature in the library files.

I did find a copy of the sldflp file located here:

C:\Program Files\SolidWorks Corp\SolidWorks\Toolbox

How do I move it so it shows up inn the task pane?

Any suggestions?
