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.

What to Do If an Error Occurs When Running the oCam Installer

When installing or running oCam, you may see an error message like the one below:


"Access violation at address XXXXX in module 'oCamXXXX.exe'. Write of address 00401000"


This error usually occurs when an anti-cheat program such as GameGuard is running. GameGuard uses system resources exclusively to protect the game, and this can interfere with the installation or execution of oCam. To resolve this issue, follow the steps below:


1. Completely close the game that is currently running. When the game closes, GameGuard will also close.

2. To make sure both the game and GameGuard have fully closed, open Task Manager (Ctrl + Shift + Esc) and check whether any related processes, such as GameGuard processes, are still running. If any remain, end those processes manually.

3. After GameGuard has closed, try installing or running oCam again.


By following the steps above, you can resolve the conflict caused by GameGuard and install or run oCam normally. If the problem continues, restart your computer and try installing oCam again without launching the game.
