S1A Troubleshooting
Common S1A Opening Problems
Unsealer Removed
You encounter an error message such as "%%os%% Can't Open S1A Files" when trying to open your S1A. Customarily, this means that Unsealer is not installed on %%os%%. The OS won't know what to do with your S1A file, so double-clicking to load the file doesn't work.
Tip: If you don't have Unsealer installed, and you know of another program to open your S1A file, you can try opening it by selecting from the programs listed under "Show Apps".
Unsealer is Out-of-Date
In other instances, your Sealed Acrobat Document file version may not be supported by your version of Unsealer. Installing the latest version of Unsealer from Oracle Corporation is recommended. This issue mainly occurs when your Sealed Acrobat Document file was created by a newer version of Unsealer than you have on your PC.
Tip: Investigate your S1A file by right-clicking and selecting "Properties" to find clues on what version you need.
Summary: In either case, the majority of problems opening S1A files are related to not having the correct software application installed on your computer.
Associated Difficulties Loading S1A Files
Even with the correct version of Unsealer installed, you can still experience difficulties opening S1As. There can be other issues - unrelated to software - preventing you from opening S1A files. Issues that aren't software-related:
- S1A file references in the Windows Registry are broken
- Unintentional removal of the description of the S1A file inside the Windows Registry
- Corrupt install of Unsealer or other S1A-related program
- Your S1A can't be loaded properly (file corruption)
- S1A file integrity has been compromised by malware
- Hardware related to S1As has device driver corruption
- Your computer does not have the adequate system resources to open the Sealed Acrobat Document format
