Troubleshoot ACT Files

Troubles Opening ACT Files

Unknown Software Disappeared

When you double-click your ACT file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Unknown Software missing in %%os%%. This will prevent you from double-clicking to open the ACT file because the OS doesn’t know how to handle it.

Tip: If you have another software that you know opens ACT files, you can select it by hitting the "Show Apps" button.

Incorrect Unknown Software Version

In other instances, your ADPCM Compressed Audio File file version may not be supported by your version of Unknown Software. Installing the latest version of Unknown Software from Unknown Developer is recommended. This problem is predominately due to having a ADPCM Compressed Audio File file version that was created by a newer version of Unknown Software than what you have installed on your PC.

Tip: Sometimes you can get a clue about the version of ACT file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

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

Additional ACT Opening Issues

You can still experience errors opening ACT files even with the latest version of Unknown Software installed on your PC.

• Invalid ACT file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Accidental deletion of the description of the ACT file in the Windows registry
• Invalid installation of a ACT-associated program (eg. Unknown Software)
• ACT file corruption
