# Fancytooltip error during fancy-preview

I wanted to try the fancytooltips package. I did the installation according to this page. I installed perl and the required Config::IniFiles library. I tried the installation both on Fedora using Texlive 2016 and on Windows 7 using MikTeX. The error is the same when calling the perl-script fancy-preview in this way: perl fancy-preview myfile

! Undefined control sequence.
l.526 \pdfximage{\TooltipFilename
.pdf}%
?
! Emergency stop.
l.526 \pdfximage{\TooltipFilename
.pdf}%


Related to this, warning was thrown:

Package fancytooltips Warning: ** The filename with tooltips is not given. ** on input line 198.


I tried it for hours, in vain. Here is my minimal (non-)working example (myfile.tex):

\documentclass{article}

\usepackage{amsmath}
\usepackage{hyperref}
\usepackage{fancytooltips}

\begin{document}

$$x^2 + y^2 = 1 \label{eq:circleEquation}$$


The fancytooltips package must be called with the inactive option. Then it compiles.
