# how to fix the error below: I was trying to download Adobe reader, after downloading, I can't open it. It says: system incompatibility

Hi Ophney Neus,

The “system incompatibility” message usually means the Adobe Reader version installed doesn’t match your system configuration (for example, architecture or supported Windows version), so Windows prevents it from launching.

Here are some possible checking steps that you can try at this point:

1, Reinstall using a compatible version

• Uninstall Adobe Reader from Settings > Apps
• Restart your PC
• Download it again from the official site and install the default recommended version

2, Check your system type

• Go to Settings > System > About
• Confirm whether your system is 64-bit or 32-bit
• Make sure the installed version matches your system type

3, Use Windows compatibility repair

• Go to Settings > System > Troubleshoot > Other troubleshooters
• Run Program Compatibility Troubleshooter and select Adobe Reader

If you need to open PDFs right away, you can use Microsoft Edge, which supports PDF files without additional installation.

Hello,

Regarding the error message:

//

Click OK or accept the option to open with AppContainer disabled --> Go to Menu / Edit > Preferences --> Select Security (Enhanced) from the left panel --> Uncheck Enable Protected Mode at startup --> uncheck Run in AppContainer --> Click Ok and restart the app

//

If you are trying to fresh install it:

Do not use the standard Adobe landing page. Download the full package directly from the Adobe Acrobat Alternative Downloads Page.

(Open Download Page --> Mode Download Options (try to download the offline package (x32 or x64).

Right-click the downloaded setup file and select Run as Administrator

• Right-click your new Adobe Acrobat desktop icon and select Properties --> Click the Compatibility tab --> Uncheck the box that says Run this program in compatibility mode

Best,
