Error Message: Acrobat could not open .pdc because it is either not a supported file type or the file has been corrupted.

This error message is displayed if you try and open a .pdc file directly from Adobes File Open menu or you have associated the .pdc file extension with Adobe Acrobat.

To open a .pdc file you must double-click on the file name in Windows File Explorer or right-click on the file and select Open With PDCViewer.

Alternatively you can open a .pdc file from within the Safeguard Viewer from the File > Open menu.
