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 Record Microphone and Computer Audio Together While Recording (Windows Vista, 7, 8)

For Windows Vista, 7, and 8, normal operation may not be guaranteed because Microsoft has ended support for these operating systems. (Reference)


In the oCam main window, click the Sound button.

 

The following menu will appear, and by default, No Microphone Recording is selected.

Select the microphone you want to record. ( If your microphone does not appear in the list, refer to the instructions below. )


Once selected, the setting will be applied as shown below, and the microphone audio will be recorded together.


If the microphone device does not appear in the list above even though the microphone is connected, proceed as follows.


( If, as shown below, no microphone-related menu appears at all and only the system sound recording menu is shown, or if a microphone item appears but not all microphone devices are listed, or if you are using a separately purchased audio interface, the audio interface device rather than the default microphone device should appear in the list. If it does not, follow this procedure. )


Go to Start Menu - Control Panel.

In Control Panel, find and click Sound.

 

The following window will appear. Click the Recording tab.


In the Recording tab, right-click the white area where it says No audio devices are installed to open the pop-up menu. ( Or, if recording devices are listed but the device you want does not appear. )


Click Show Disabled Devices.


Select the microphone device you want to use, right-click it, and click Enable.

( If you are using an audio interface, a separate recording device called Line In may appear instead of a microphone, and you should record using that device. ) 


In oCam, click the Sound button to check whether the microphone device now appears correctly.
