There isn[SQ]t a specific Windows software package called "Efficient Elements for Presentations". That name doesn[SQ]t correspond to a known presentation tool or suite.

It[SQ]s possible :

*

The name is slightly different:

Perhaps you[SQ]re misremembering the name. Could it be a part of a larger suite, or have a similar-sounding name? Try searching online using variations of the name.
*

It[SQ]s a niche or internal tool:

The software might be proprietary to a specific company or organization and not publicly available.
*

It[SQ]s a newly developed tool:

If it[SQ]s very recent, it might not yet have widespread recognition.

To help me find what you[SQ]re looking for, could you provide more details? For example:

*

What kind of presentations is it used for?

(Business, education, etc.)
*

What features do you remember it having?

(Specific templates, animation styles, etc.)
*

Where did you hear about this software?

(A website, a colleague, etc.)


With more information, I might be able to help you identify the presentation software you[SQ]re thinking of.
