I am getting a situation where I am getting a fatal error: Acorbat failed to connect to a DDE server pop up box. This happens when I open a pdf file after I open one and close it. In other words I can open a PDF document in Acrobat and it works filne. I then close that PDF file. When I try to open the next PDF (after closing the first one) I get the error. I continue to get the error for each additional PDF file that I try to open. If I keep one PDF file open (the first one) then I don't get the error until I close all open PDF files. I have to restart to get Acrobat to work again.
Windows 2003 server SP2 (x64)
Citrix XenApp 5.0
Adobe Reader 9.3
Adobe Acrobat Standard 9
I installed Acrobat first then reader.
