Error 523 Adobe Reader

Hi All,

I have a strange problem. I have a smartform that I convert in pdf binary and show in a container with cl_gui_html_viewer. In this "tool" i can show several pdf triggering some events (button, double click...) Everything fantastic since 1 week ago. Then an update of Adobe Reader DC came and now is not anymore fantastic. the following message appear when i try to show the pdf as usually. "There is problem with Acrobat / reader. If it is running, Please exit and try again(523:523)" I checked on internet and the only solution i found is turning off "Edit-->preferences-->general-->Enable protected mode at start up". Actually it works, but now it is very slow showing up the pdf. And also is not very good to say to a customer to turn off the Protect Mode. If i reinstall Adobe the problem there is not anymore, but after a day the update comes and the problem too. My colleague who have other versione (like 9) of Adobe do not have this problem.

Actually I'm not sure at all, however, the problem is not in my code. Because the first time i show the pdf there is no problem and it is fast (also without turn off the Protected Mode). All the others times i try to do something to show others pdf i have the problem described above (error 523 with Protect Mode on, and slow when Protect Mode off). I tried to free the html_viewer every time i show a pdf but nothing changed.

Some ideas?

Thanks a lot

    Check the below option ?
    Its because you are using the file as an administrator, just go to adobe, right click and click properties and then in settings untick the tickbox saying run this program as admin. worked for me!

    We have similar problem - although no crash, as we do not run as admin, but SAP PDF preview is very slow (20 seconds per document) on actions back or cancel. Problema happened after adobe DC patch 2015.023.20053. Adobe forum is full of SAP customers complains on that, but still adobe provided no solution. I registered problem to SAP - but no solution aswell.

    Our workarand is to replace ADOBE DC with XI

    Thank you Vijaya but it didn't work for me.

    Thank you Ramunas for let me know the situation, I'll wait and meanwhile I'll try to change in XI too.

    Best Regards

    Hi all,

    just for information i want to share.

    If there is a session showing a pdf document on my module pool and I open another session always on my module pool working on pfd, I have no problems.

    So, more strange than i expected. One session very slow. More sessions very fast... :-/
