I have the same problem on XP SP3 system, brower is FireFox 52.09.0.
Recently re-install the system, but cannot install flash player and reader, got "initilalsing failure". Could you please provide some suggestion, is that a bug for XP sp3? Any fix is arranged?
I branched your post as the "initialization error" is not related to the topic you posted to.
To troubleshoot, please provide the following files:
Upload the files to Document Cloud (see How to share a file using Adobe Document Cloud) or some other file sharing service of your choice that doesn't require account log-on access. Post the link to the uploaded files in your reply.
