Adobe Reader 11 MUI - signing documents

Hi Guys,

we are using adobe reader 11.0.18 mui and we are having problem with signing documents. Signing is working OK when Acrobat is using English language, but for other languages it not works.

Signing option is available, and also I can input initials or signature, but it will not apear in document.

As a solution I tried:

-reinstall

-update to 11.0.19

-change default install language in MST to other that English

-compare HKLM and HKCU registry (engish and german)

Still same issue.

Can someone help us? Or is it known bug?

Thanks

Martin
