EXD File Complications
Typical EXD Opening Challenges
Microsoft Excel Not Present
Double-clicking your EXD file prompts the message "%%os%% Can't Open EXD File". Generally, this is experienced in %%os%% because Microsoft Excel isn't installed on your PC. This will prevent you from double-clicking to open the EXD file because the OS doesn’t know how to handle it.
Tip: If you know of another program that can open your EXD file, you can try opening it by selecting the application from the programs listed.
Microsoft Excel is Out-of-Date
Occasionally, you might have an outdated version of Microsoft Excel installed that's incompatible with your Control Information Cache File type. Installing the latest version of Microsoft Excel from Microsoft Corporation is recommended. The primary cause of this problem is that your Control Information Cache File file was created by a different (newer) version of Microsoft Excel than what's installed.
Tip: Right-clicking on your EXD, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
Summary: Not having the right Microsoft Excel version on your computer can cause problems opening EXD files.
Other EXD File Issues
Although you might already have Microsoft Excel or another EXD-associated software installed on your computer, you can still encounter problems opening Control Information Cache File files. Other EXD opening errors can be created by other system problems inside of %%os%%. Additional factors include:
- EXD file type Registry entries are wrong
- Deletion of the EXD file description from the Registry by mistake
- Defective install of a EXD program, such as Microsoft Excel
- Your EXD file is corrupted (issues with your Control Information Cache File file itself)
- The EXD is infected with a virus
- Device drivers of the hardware associated with your EXD file are corrupt or out-of-date
- Insufficient system resources to successfully open Control Information Cache File files
