Try updating your browser to IE8 and updating Adobe Reader to the latest version. This mostly works.
Thanks for the attempt, but I tried it already and it didn't work.
then try disabeling the SSL and TLS in the browser. Restart the PC and reenable it.
Thanks for your help, I’m trying to do it, but it doesn’t work.
The only difference between the two cases is that in the working case, the form is opened with Adobe Reader inside a browser, and in the not working case, as the form has been stored in the hard-disk, it’s opened directly with Adobe Reader without using any browser.
Is it possible to send a client certificate using Adobe Reader outside of the browser? How does it work? Does a window pop-up so that you can choose a certificate?
