I recently upgraded Adobe Acrobat XI, and since then, I have been unable to view LyX files and to export them, as the following warning message displays:
File does not exist:
I've already tried to uninstall and install LyX and MiKTeX several times, as well as deleting all preferences and all register entries, but nothing works. If it is an Adobe Acrobat problem, I have to point out that it works perfectly but for this problem.
What can I do to solve it?
Thank you in advance
