CU Troubleshooting

Common CU Opening Problems

Microsoft Notepad is Not Installed

Double-clicking your CU file prompts the message "%%os%% Can't Open CU File". If this is the case, it's usually due to the fact that you do not have Microsoft Notepad for %%os%% installed on your computer. You won't be able to double-click to open your CU because your OS doesn't know what to do with it.

Tip: If you don't have Microsoft Notepad 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".

Incorrect Microsoft Notepad Version

Occasionally, you might have an outdated version of Microsoft Notepad installed that's incompatible with your CUDA Source Code File type. If you've got the wrong version of Microsoft Notepad installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

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

Conclusion: The majority of CU file opening issues are due to not having the correct Microsoft Notepad version installed.

Other CU File Issues

Although you might already have Microsoft Notepad or another CU-associated software installed on your computer, you can still encounter problems opening CUDA Source Code File files. If you are continuing to have errors with loading CU files, other external issues might be to blame. Other contributing causes:

• CU file type Registry entries are wrong
• Corruption of the CU file description inside the Registry
• Corrupt install of Microsoft Notepad or other CU-related program
• CU file corruption
• Malware-tainted CU file can't be opened
• Device drivers for CU-related hardware are out-of-date
• Windows cannot load your CUDA Source Code File file due to insufficient resources (eg. RAM)
