What to Do If the "Failed to get path of 64-bit Common Files directory" Error Occurs When Installing oCam

Using oCam at work or school? A license is required, and it removes all ads, including this window. See the paid version →

In some cases, you may need to modify the Windows Registry to fix an oCam setting or issue. Below is a detailed explanation of how to use the Registry Editor to add the required key values.


1. Press Windows key + R on your keyboard to open the Run dialog box.

2. Type `regedit` in the Run dialog box and click the 'OK' button to launch the Registry Editor.

3. When the Registry Editor opens, follow the instructions in the video below to complete the required settings:

4. As instructed in the video, add the following Registry key values:  

   - CommonFilesDir: `C:\Program Files\Common Files`  

   - ProgramFilesDir: `C:\Program Files`

5. After adding the Registry key values, close the Registry Editor and restart your computer to apply the changes.


Because editing the Registry directly affects system settings, it is important to back up the Registry before making changes or follow the instructions in the video exactly. The added key values help oCam reference the correct file paths and can be useful for resolving certain installation or launch issues. After completing the steps, run oCam and check whether the problem has been resolved.

How to Ensure Recorded Videos Can Be Recovered Even If the App Is Force-Closed During Recording

When recording video with oCam, selecting the MKV container from the Codec menu allows the video file to be saved more safely even in unexpected situations. The MKV container offers excellent file stability, so even if the program closes during recording due to various issues, the file will not be corrupted and can still be played normally.

 

For example, even if oCam is force-closed during recording, or if a game suddenly crashes while recording gameplay, the video file saved in the MKV container can still be played normally. This is possible because the MKV format is designed to store data in a highly stable file structure.


On the other hand, if you use the MP4 container, the file may become corrupted and impossible to recover in the same kind of abnormal shutdown situation. For stable recording, using the MKV container is recommended.


However, there are a few things to keep in mind when playing MKV files. If you play an MKV file in Windows Media Player, the seek function, such as jumping to a specific point in the video, may not work smoothly. Playback itself works without a problem, but for better seeking convenience, it is recommended to use an external video player such as PotPlayer. PotPlayer plays MKV files reliably and also supports smooth seeking.


Also, MKV files are not supported by Naver's video upload feature. Since the Naver platform does not allow MKV uploads, you will need to use a platform such as YouTube if you want to share videos on the web. YouTube supports MKV uploads without issues and provides an environment optimized for sharing and playback.


Therefore, if you want stable recording with oCam, the most effective method is to select the MKV container from the Codec menu, use an external player such as PotPlayer for playback, and use YouTube for web sharing.
