Windows - Application Error beim Öffnen von PDFs

New Here ,
Oct 13, 2025 Oct 13, 2025

Hallo! 

Wir haben bei vielen Kollegen das gleiche Problem seit ca. 2 Wochen. 

Sobald eine PDF geöffnet wird und Adobe Acrobat Reader startet erscheint folgende Fehlermeldung:

Adminsw_0-1760356979659.png

Diese Fehlermeldung erscheint gesamt 4 mal. Nachdem man 4 mal auf "OK" geklickt hat, ist sie weg und das PDF kann ganz normal angeschaut werden. 

 

Folgendes haben wir bereits ausprobiert zur Fehlerbehebung:

Aktuellste Version von Adobe Reader installiert -> ohne Erfolg

Microsoft Visual C++ geupdatet -> ohne Erfolg
komplett deinstalliert und neu installiert -> ohne Erfolg
Windows Updates überprüft -> keine verfügbar
Adobe Ordner im Registry Editor gelöscht -> ohne Erfolg
versucht als Admin ein PDF zu öffnen -> auch dann erscheint die Fehlermeldung
sfc /scannow ausgeführt -> ohne Erfolg

 

Woran kann dieses Problem noch liegen? Wer hat einen weiteren Lösungsvorschlag? 

 

Vielen Dank im Voraus!

@Admin-sw it sounds like it's a local compatibility or configuration conflict. With the error appearing consistently when opening PDFs and disappears after clicking “OK” several times it suggests a recurring memory or runtime issue within the application itself, possibly tied to how Acrobat Reader interacts with Windows 11 or specific system libraries. A couple work-arounds, disable Protected Mode at startup in Acrobat Reader (under Preferences > Security (Enhanced)). This can sometimes resolve

A couple work-arounds, disable Protected Mode at startup in Acrobat Reader (under Preferences > Security (Enhanced)). This can sometimes resolve memory-related errors, especially if they’re triggered by sandboxing conflicts. Second work-around, to switch to the 32-bit version of Acrobat Reader if you’re currently using 64-bit, as some users have reported better stability.

@creative explorerThanks a lot for your help! Disabling Protected Mode didn’t solve the issue, but after switching to the 32-bit version everything is running smoothly without the error.
