Hi,

Code 45

Currently, this hardware device is not connected to the computer. (Code 45)
This error occurs if a device that was previously connected to the computer is no longer connected. To resolve this problem, reconnect this hardware device to the computer.

No resolution is necessary. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. The error code resolves automatically when you connect the associated device to the computer.

Additional information

If Device Manager is started with the environment variable

DEVMGR_SHOW_NONPRESENT_DEVICES
set to 1 (which means show these devices), any previously attached (NONPRESENT) devices are displayed in the device list and assigned this error code.

Code 38

Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
The driver could not be loaded because a previous instance is still loaded. Restart the computer.

38-character "product code"

I ran the troubleshooter for uninstalling a program that isn't listed in Windows 10 apps list that is described at Fix problems that block programs from being installed or removed

The troubleshooter asks for a 38-character product code.

To find the code, I tried running this command in a command prompt and an administrative command prompt:

Get-WmiObject -Class Win32_Product

That was not recognized as a command. Next, in Powershell, I ran
Get-WmiObject -Class Win32_Product. I got a list of installed apps with 38-character codes, but the one that I want to uninstall was not on the list.

What should I try next?
