With the release of Adobe Acrobat 64 bits (Pro and Reader) you may have faced various rendering issues.
This could be due to the missing DirectX 9 renderer.
Adobe has since implemented DirectX 9 in the 64 bits versions.
- You can verify that the renderer is set to DirectX 9 in :
Edit → Preferences → Multimedia & 3D
- If not present, please check that Adobe Acrobat is up to date in :
Help → Check for Updates
- If you face a message stating “How to activate DirectX9”
This means that you do not have the DirectX component on your PC.
Please download and install it from the official Adobe Acrobat website : Download DirectX 9 to render 3D files in Acrobat and Acrobat Reader
- If you face behavioral issues (button or cross-highlight not working)
Please verify that the default Adobe Acrobat Pro setting in Edit → Preferences → Security (Enhanced) → “Enable Protected Mode at startup” is DISABLED.
