Error 0x800704b3 when launching application from HFS+ volume

Error code: 0x800704b3

The network path was either typed incorrectly, does not exist, or the network provider is not currently available. Please try retyping the path or contact your network administrator.

This error appear when user runs .exe\.msi file from HFS+ mounted volume in Windows.

It’s a common error usually appearing when WebClient service is not running:

1. Right click Computer and click on Manage. The Computer Management window should appear.
2. In the console tree box at the left, click on Services and Applications, then click on Services. A list of services should appear.
3. Scroll down until you find WebClient.
4. Right click it and click on Properties.
5. Under the General tab click on Start. If you want to have the service start automatically as part of the Windows boot process, then set the Startup type to Automatic.

The alternative workaround is connected with registry editing.

1) Run regedit to enter the registry.

2) Navigate to

HKLM\SYSTEM\CurrentControlSet\Services\Hfsplus\

And create new key with the name “parameters”

3) In HKLM\SYSTEM\CurrentControlSet\Services\Hfsplus\Parameters\

Create new string value with the name “Fake FS Name” – use modify and set Value data to “CDFS” as described in screenshot below.

4) Reboot.
