(HELP) AutoSaveFileCmd: Open generated PDF automatically after saving

[adrian422]

Hello,

I am currently configuring PDF24 Creator 11.30.1 x64 for a silent/machine-wide installation.

The PDF24 printer is configured with:

<code class="language-reg">[HKEY_LOCAL_MACHINE\SOFTWARE\PDF24\Services\PDF]
"Handler"="autoSave"
"AutoSaveDir"="C:\\Temp\\PDF24Test"
"AutoSaveFilename"="%Y-%m-%d %H-%M-%S $fileName"
"AutoSaveUseFileCmd"=dword:00000001

Automatic saving works correctly.

I also verified that AutoSaveFileCmd is executed. For example:

<code class="language-reg">"AutoSaveFileCmd"="cmd.exe /c echo TEST >> C:\\Temp\\pdf24-command.txt"

creates the file successfully.

I also verified that ${file} is substituted correctly. It contains the complete generated PDF path, for example:

<code class="language-text">C:\Temp\PDF24Test\2026-09-14 12-49-10 -Lorem ipsum dolor sit amet, consete - Notepad.pdf

My problem is that I want to automatically open the generated PDF with the user's default PDF application after saving.

I have tried:

<code class="language-reg">"AutoSaveFileCmd"="\"C:\\Program Files\\Adobe\\Acrobat DC\\Acrobat\\Acrobat.exe\" \"${file}\""

and even:

<code class="language-reg">"AutoSaveFileCmd"="\"C:\\Program Files\\Adobe\\Acrobat DC\\Acrobat\\Acrobat.exe\""

but Acrobat does not open.

I also tried:

<code class="language-reg">"AutoSaveFileCmd"="cmd.exe /c start \"\" \"${file}\""

but nothing happens.

Interestingly, simple commands such as echo work, so AutoSaveFileCmd itself is definitely executed.

Is there a recommended way in PDF24 Creator 11.30.1 to launch a GUI application / the user's default PDF viewer from AutoSaveFileCmd after an auto-save?

Would using a separate PDF24 printer/service make a difference, or is there another command/syntax specifically intended for opening the generated PDF?

Thank you!
