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.

oCam Closes Automatically a Few Seconds After Launching

When trying to record with oCam, a specific issue may occur if an online video lecture site is running. This problem is usually caused by anti-recording software used by the site to protect its content. Below is a detailed explanation of the issue and how to handle it.


Online video lecture sites often use anti-recording software to protect copyrighted content. This software detects recording programs such as oCam and force-closes them at regular intervals. As a result, oCam may not be able to continue recording normally or may close unexpectedly.


To resolve this issue, you need to contact the online video lecture site directly where you want to record. Ask the site operator whether recording is allowed and check their related policy. If necessary, request permission to record. Some sites may allow recording under certain conditions or provide a way to temporarily disable the anti-recording feature.


Attempts to bypass issues caused by anti-recording software may violate the site's terms of use, so it is important to follow the site's policy. Therefore, if you want to record lecture content with oCam, first consult the site administrator and follow the proper procedure.
