Our client has a Terminal Server environment with Microsoft Windows 2008 Operating system and they use Adobe Pro XI product on their server. For some reason, the Adobe will ask them to sign in/register every day. I tried to uninstall and re-install the product by downloading it from the login portal, but it gave me some errors which said: "ERROR 1911. Could not register". I have the screenshots if you need them.
After I install when the users are trying to open any .pdf files the document will be closed and adobe registry screen will pop-up
