32-bit and 64-bit Support

PDF Reader Pro supports both 32-bit and 64-bit versions of Windows.

Both editions are included in a single installation package, and the installer will automatically detect your system type and install the correct version — no manual selection is required.

Installation Note

The 64-bit version of Windows can process larger amounts of RAM and handle more data at once than the 32-bit version, which may improve overall performance.

For the best experience, we recommend running PDF Reader Pro on a 64-bit Windows system whenever possible.
