Can't uninstall PDF24: it says PDF24 is still running

[PDF24]

I cannot uninstall pdf 24

When I try to uninstall using the Add or remove programs function I get a dialog box saying pdf 24 is running when it is not. How do I close it down so I can uninstall it?

Hi,

this was a problem in version 2.6. I think you have this version installed. We have corected this problem in version 2.6.1.

The problem ist that a background process named pdf24.exe is still running. The uninstaller will not remove the program unless all components are closed. To close this background process right-click the pdf24 tray icon and choose the close entry there. Than you can uninstall PDF24 Creator. You can also use your task manager to close pdf24.exe.

The background process is needed to handle print jobs and therefore to create PDF files if you print something on pdf24 printer.

I updated my old version of PDF24 by installing the 2.6.3 version over it. Now my PDF Printer disappeared. I tried to unistall once and reinstall, but it didn't work. What can I do to have the PDF24 printer back? I use de Windows XP.

Love this program but can't upgrade. Whenever I download the upgrade I get a message to close existing running version of PDF24 - message produced even when pdf24 isn't running. Have tried uninstalling existing version, but when attempting the uninstall I get the same message, also preventing that uninstall.

Existing Program seems to work OK, except it always produces the upgrade message first on opening (or printing to pdf). That message then needs to be closed before proceeding to use the existing program version.

I am trying to install the latest Update for the program but it keeps telling me that there is a version of the program that is open and must be closed. The only version of the program open is the exe file. I have confirmed this via the system task master.

What do I need to to do update this program????

Close every process which has something to do with pdf24. All PDF24 process contains the name pdf24, like pdf24.exe or pdf24-Creator.exe. CLose all these processes, also processes from other users. In the taskmanager you have to check "Show all process" to see all the processes of your Windows. If that does not help, try a reboot.

Maybe the PDF24 Windows Service that blocks. Try to stop this service with the Windows services UI. Or enter the task manager and kill all pdf24 processes.

Not sure how to reply to your answer, stefan 614. But thanks for your very prompt answer. Using the uninstall (windows 7),I used the task manager to kill the relevant processes. That worked a treat. Old version uninstalled and version 9 now successfully installed. Thanks again. Nick Scott.

Hello,

a note for readers who find this topic today: since version 11.31.0, the PDF24 Creator setup closes the PDF24 background processes itself before installing, also those in other user sessions (fast user switching, terminal server). If the setup still reports that PDF24 Creator is running, PDF24 programs are still open, possibly by another signed-in user. Close them, or end the pdf24 processes in Task Manager as described above.
