Sources of ADT Problems


Common Problems Opening ADT Files

Swiftpage Act Disappeared

You encounter an error message such as "%%os%% Can't Open ADT Files" when trying to open your ADT. Generally, this is experienced in %%os%% because Swiftpage Act isn't installed on your PC. You won't be able to double-click to open your ADT because your OS doesn't know what to do with it.


Tip: If you know of another program that can open your ADT file, you can try opening it by selecting the application from the programs listed.


Outdated Swiftpage Act

Occasionally, you might have an outdated version of Swiftpage Act installed that's incompatible with your ACT! Document Template type. If you do not have the proper version Swiftpage Act (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. Your ACT! Document Template file was probably created by a newer release of Swiftpage Act than what's currently installed your computer.


Tip: Right-clicking on your ADT, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.


Summary: In either case, the majority of problems opening ADT files are related to not having the correct software application installed on your computer.


Other ADT File Issues

You can still experience errors opening ADT files even with the latest version of Swiftpage Act installed on your PC. There can be other issues - unrelated to software - preventing you from opening ADT files. Other contributing causes:

  • Invalid ADT file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Mistaken removal of the Windows registry ADT description
  • Corrupt install of Swiftpage Act or other ADT-related program
  • The ADT itself is corrupted
  • ADT file integrity has been compromised by malware
  • ADT-related hardware has device drivers that obsolete
  • Your computer does not have the adequate system resources to open the ACT! Document Template format

Quiz: Which operating system pioneered hierarchical file system (eg. file folders)?
