Invalid configuration registry key

By ccomer ·
I was trying to install a printer through a usb port on my computer and it starts to go through the process just fine and starts to download the drivers only to finish by saying device may not work properly then under that it says configuration registry key is invalid. Then when I check under the device manager it has a black exclamation mark in a yellow field over that usb port. This is not the first time I have had usb issues with this computer. Any help would be greatly appreciated.

Invalid configuration registry key

by tbiz0 In reply to Invalid configuration reg ...

I am having the same error and it is affecting my ability to install and uninstall software. Microsoft's website just says "The system is unable to open or create a Registry key that does not have a name. Provide a key name" as if it is deep secret or only software programmers should be trying to resolve it.

As example to help us determine what key to provide a name to would certainly help. Here is the setupapi.log record.

#-198 Command line processed: "C:\WINDOWS\system32\rundll32.exe" setupapi.dll,InstallHinfSection Uninstall 128 C:\WINDOWS\inf\oem38.inf
#-011 Installing section [Uninstall] from "C:\WINDOWS\inf\oem38.inf".
#E033 Error 1010: The configuration registry key is invalid.
#E065 Parsing DelReg section [pid_0920.addreg] in "C:\WINDOWS\inf\oem38.inf" failed. Error 1010: The configuration registry key is invalid.
#E064 Parsing install section [Uninstall] in "C:\WINDOWS\inf\oem38.inf" failed. Error 1010: The configuration registry key is invalid.

Invalid Configuration Registry Key

Here is what I did dot solve this. The problem was with some missing XP SP2 files and an error in the validation of the configuraton registry key. Though I have a Genuine copy of Windows XP, somehow it didn't get fully communicated across all the dll files in my computer. If you have errors in c:\windows\setupapi.log like the ones below in the installation of any software, you may not get a clean install of Quickcam drivers:
- an unsigned or incorrectly signed file Error 0x800b0100,
- configuration registry key is invalid Error 1010,
- not an approved method of installing INF files #E197, or
- access is denied Error 5.

To reload missing Windows XP SP2 files, I performed the following as per guidance at;
1. Disable any software which runs at startup like antivirus, updates, etc.
2. Start>Run>cmd [enter]>sfc.exe/purgecache [enter] (to clear the cache which could be corrupted)
3. Start>Run>cmd [enter]>sfc.exe/scannow [enter] (to replace all missing or damaged XP SP2 files, have XP disk in drive).
4. Reboot the system

Then to correct the installation errors follow the steps here:

Lesson learned: when Windows gets confused it can take hours to figure out the problem, then fix it.

my experience with usb printers you are instructed to install the sofware before connecting the printer to the pc.OS and printer model wouldn't go astray. Is the OS compatiable with the printer?
