Solution 1: Install the product as an administrator

When you install the product, you’re required to install the hcmon driver. Windows may see this as a user adding hardware to the PC. But this user doesn’t have the permission to do that. In this case, this error may occur. Try to install the product as an administrator:

1) Right-click on the downloaded setup file.

2)  Click Run as administrator. If you don’t see the option “Run as administrator”, this solution doesn’t apply to you. Skip then move on to other solutions.

3) Click the Update button next to the flagged drivers to automatically download and install the correct version of their driver (you can do this with the FREE version). Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

Solution 3: Remove the hcmon.sys driver

The HCMON driver might be installed. One possible solution is to remove the hcmon.sys driver. Follow these steps:

1) Go to Device Manager.

2) Click View > Show hidden devices.

3) Double-click Non-Plug and Play Drivers.

4) Right-click hcmon and click Uninstall.

6) Delete the C:\Windows\system32\drivers\hcmon.sys file.

7) Restart the computer.

Solution 4: Install the product using PowerShell

Try to install the product in PowerShell. Follow steps below:

1) Type “powershell” in the search field. Right-click Windows PowerShell (The name may be different depending on the Windows version you’re using.) and click Run as administrator

2) Go to the location where you saved the setup file. This is to get the msi name.

3) Type .\xxxx.msi in PowerShell command prompt and press Enter on your keyboard. XXXX means the name of msi file. Replace it with your msi file name.

In my case, my file is “VMware-VMRC-10.0.1-5898794”:

So I typed “.\VMware-VMRC-10.0.1-5898794.msi”:
