Question details
Adobe Acrobat 9 Pro Extended fails to open or stops working after installing Adobe InDesign.
- Product
- Adobe Acrobat 9 Pro Extended
- Device & OS
- not provided
- Scenario
- Launching Adobe Acrobat to view or edit PDFs after installing Adobe InDesign on the same system.
- Observed behavior
- Acrobat 9 Pro Extended refuses to launch, crashes upon startup, or throws a system error preventing normal operation.
Ensure you have saved all active work in InDesign and closed any other background applications to prevent data loss while troubleshooting the software conflict.
Restart the Computer and Document the Exact Error
A system restart clears temporary installation caches, while capturing the specific error message helps identify whether the issue is related to licensing, shared libraries, or system compatibility.
Software conflicts often occur because background services linked to the newly installed program (InDesign) are holding onto shared resources. A fresh boot ensures all services start cleanly.
Save your files, close all open windows, and restart your computer entirely rather than just putting it to sleep.
Locate Acrobat 9 Pro Extended from your Start menu or desktop shortcut and attempt to open it.
If the application fails to open and presents a pop-up warning, take a screenshot or precisely write down the error code and text. This is crucial for isolating the root cause.
Run Acrobat as Administrator
Granting elevated permissions can sometimes bypass access restrictions created when a newer Adobe application alters shared folder permissions.

Frequently Asked Questions
Why does installing Adobe InDesign affect Acrobat 9 Pro?
Adobe products often share core background processes, such as the Adobe Creative Cloud desktop app, licensing services, and dynamic link libraries. Installing a newer application can overwrite these shared components with versions that older software like Acrobat 9 cannot read.
Is Adobe Acrobat 9 Pro Extended still officially supported?
No, Acrobat 9 Pro Extended reached its end of life many years ago. It no longer receives security updates or compatibility patches, making it prone to launching issues on modern operating systems or when run alongside newer software.
Does installation order matter for Adobe software?
Yes. As a general rule for legacy software, you should install older Adobe applications first, followed by the newer ones. This ensures that any shared background components installed by the newer software remain intact.
Can I have both programs on the same computer without crashing?
Yes, but if conflicts arise due to drastically different version ages (e.g., CS4 era Acrobat alongside CC era InDesign), you may need to rely on separate systems, virtual machines, or alternative PDF viewers to maintain stability.
