Subject: TC8.01, Acrobat Reader DC - can't open pdf files from TC
Posted: Mon Mar 21, 2016 5:25 am (GMT -6)
First, please be excused for my poor English!
I work with Windows10 and administrative rights. When I came across the problem, I started and Task Manager to observe what is happening.
TC is installed in "Program files".
PDF files are associated with Acrobat Reader DC as default.
1. When I double click on pdf file in File Explorer (i.e. Windows Explorer), the file is opened. Task Manager shows that is started the application "Adobe Acrobat Reader DC" and tree background processes "Adobe RdrCEF".
Now if double clik on pdf file in TC, the file also is opened and Task Manager shows that is launched another process "Adobe RdrCEF".
If I close both pdf files, running processes and application are also closed.
2. If the application Acrobat Reader DC is not runing and I double click on the pdf file, the file does not open and Task Manager shows that are started only two background processes "Adobe Acrobat Reader DC".
Now if I double click on another pdf file in TC, nothing happens, but if I double click on pdf file in File Explorer, Task Manager shows that is launched another two background processes "Adobe Acrobat Reader DC". If I again double click on another pdf file in File Explorer, Task Manager shows that is launched another two background processes "Adobe Acrobat Reader DC". And so on.
Since no application is started, these background processes can be terminated only by Task Manager.
After 5-10 min. background process, launched from File Explorer show window "Fatal Error" with message "Acrobat failed to connect to a DDE server" and when close window, process is closed. Background processes launched from TC can be terminated only by Task Manager.
3. If I click in TC on pdf file with right mouse button and select "Open with/Adobe Acrobat Reader DC", happens the same as in point 2.
4. If I click in TC on pdf file with right mouse button and select "Open with/Choose another App/" and then select "Adobe Acrobat Reader DC", the file is opened normally.
Now if I double click on another pdf file in TC (and in File Explorer), it also is opened normally.
Although on opening of the file in this way checkbox "Always use this app to open .pdf files" is marked, after closed once the app, the situation remains the same as in point 2.
Any ideas to solve this problem?
