Troubles Opening IKO Files

ICON resource Isn't There

You attempt to load your IKO file and get an error such as "%%os%% Can't Open The IKO File Extension". If this is the case, it's usually due to the fact that you do not have ICON resource for %%os%% installed on your computer. This will prevent you from double-clicking to open the IKO file because the OS doesn’t know how to handle it.

Tip: Another IKO-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Wrong Version of ICON resource is Installed

In other instances, your Windows Icon Resource File file version may not be supported by your version of ICON resource. Installing the latest version of ICON resource from Microsoft Corporation is recommended. Your Windows Icon Resource File file was probably created by a newer release of ICON resource than what's currently installed your computer.

Tip: Investigate your IKO file by right-clicking and selecting "Properties" to find clues on what version you need.

Primarily, problems experienced when opening IKO files are due to having the incorrect version of ICON resource installed on your computer.

Additional IKO Opening Issues

In the majority of cases, installing the right version of ICON resource will resolve your issue. There can be other issues - unrelated to software - preventing you from opening IKO files. These issues include:

• Invalid IKO file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• The IKO file description within the Windows Registry was removed
• Invalid installation of a IKO-associated program (eg. ICON resource)
• Your IKO can't be loaded properly (file corruption)
• IKO file integrity has been compromised by malware
• Hardware related to IKOs has device driver corruption
• Windows cannot load your Windows Icon Resource File file due to insufficient resources (eg. RAM)
