If you receive any error messages such as "Device for EuMusDesign_VAC_WDM_jrm already installed", you will need to run the above command from either step 5 or 9 replacing the -i with a -r to remove the current faulty installation (e.g. wdmdrvmgrx86.exe -r EuMusDesign_VAC_WDM_jrm vacjrmkd.inf) and then after a few moments, run the command with the -i from step 5 or 9 to install the MuvEnum Virtual Cable successfully.

• Click "Ok" to close this window.
• Once you have changed this, please rerun the MuvAudio installation and the installation for "MuvEnum Virtual Cable" should run and you should be able to now use MuvAudio.

This means that the driver.cab and/or sp2.cab file(s) are missing from your Windows\Driver Cache\i386 folder.

4. Click OK
5. Now, if you see the Copy Error prompt, click on the Browse... button.
6. Navigate to your Windows directory, then to the System32 directory, and then to the Drivers directory.

8. If there are multiple prompts, continue pointing to the c:\windows\system32 and c:\windows\system32\drivers directories until no more errors show up.
9. Once no more prompts are shown, you have completed the manual steps to install the MuvEnum Virtual Cable successfully and should be able to run MuvAudio.
