~CU File Complications

Frequent ~CU Opening Issues

Missing ACD Systems ACDSee

When you double-click your ~CU file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have ACD Systems ACDSee for %%os%% installed. This will prevent you from double-clicking to open the ~CU file because the OS doesn’t know how to handle it.

Tip: If you don't have ACD Systems ACDSee installed, and you know of another program to open your ~CU file, you can try opening it by selecting from the programs listed under "Show Apps".

ACD Systems ACDSee is Out-of-Date

In some cases, you might have a newer (or older) version of a Windows Cursor File file that is unsupported by your installed application version. Visit the ACD Systems website to download (or purchase) the latest version of ACD Systems ACDSee. Most of the time your Windows Cursor File file was created by a newer ACD Systems ACDSee than what you have installed.

Tip: If you right-click on your ~CU file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Ultimately, most of the difficulties opening ~CU files are due to having the wrong version of ACD Systems ACDSee installed.

Other ~CU File Opening Causes

You can still experience errors opening ~CU files even with the latest version of ACD Systems ACDSee installed on your PC. If you're still experiencing problems opening ~CU files, there could be other computer problems. These other problems include (listed in order from most to least common):

• ~CU file references in the Windows Registry are broken
• Accidental deletion of the description of the ~CU file in the Windows registry
• Partial installation of ACD Systems ACDSee that did not fully complete
• Your ~CU can't be loaded properly (file corruption)
• Your ~CU is infected with malware
• Hardware associated with ~CU has outdated drivers
• Windows cannot load your Windows Cursor File file due to insufficient resources (eg. RAM)
