Apple Event as it happened | Apple October Event live blog: Apple unveils new MacBook Pro at…
Next door called me with a problem last week as her scanner had stopped working - I couldn't get it to work. She bought a new Epson and tried to install. All went well until plugged in and Windows couldn't install the software. Thought I'd check device manager. Totally blank. Tried suggestions on Google - start P&P in services - already running. Edit a registry key - already as the suggestion. Seems there was nothing wrong with the old printer, just a glitch in Windows somewhere.
I feel a re-install may be the answer, but thought I'd check if anyone has come across this and has an alternative solution.
Don't know how you are doing it but the software is normally installed first before plugging in the scanner.
If the Device Manager is till showing empty list try the following -
- Click Start, click Run, type services.msc, and then click OK.
- Double-click Plug and Play. (If you receive a Configuration Manager message, click OK.)
- In the Startup Type list, click Automatic, and then click OK.
- Close Services.
- Restart the computer.
Looks as if you have lost permissions to view devmngnt
Back up everything first before you:
Reset Vista default permissions, then grant permissions to your admin user account (the one you normally use OK). Try the following steps.
Download the subinacl.msi file to your desktop
On the Desktop and double click the downloaded file.
Select the C:\Windows\System32 folder as the Destination Folder during the installation. Later this tool is used to reset the permission settings on the current machine.
Note: If UAC (User Account Control) window is prompted for permission to continue, please click "Continue"
Click "Start". In the Start Search bar, type: notepad and press Enter.
Copy the following commands and then paste them into the opened Notepad window:
subinacl /subkeyreg HKEYLOCALMACHINE /grant=administrators=f
subinacl /subkeyreg HKEYCURRENTUSER /grant=administrators=f
subinacl /subkeyreg HKEYCLASSESROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subdirectories %windir%*.* /grant=administrators=f
subinacl /subkeyreg HKEYLOCALMACHINE /grant=system=f
subinacl /subkeyreg HKEYCURRENTUSER /grant=system=f
subinacl /subkeyreg HKEYCLASSESROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f
subinacl /subdirectories %windir%*.* /grant=system=f
After the above commands are finished, close the Notepad window. Choose Save when you are prompted to save the file. Type "reset.bat" as the file name and choose Desktop from the left panel as the save location.
Refer to the Desktop and right click the reset.bat file, then choose "Run as administrator."
You should see a DOS-like window processing.
NOTE: It may take several minutes. When it is finished, you will be prompted with the message: "Finished, press any key to continue".
Now to reset your user permissions:- log in as your normal user
Go to start, all programs, accessories and right click on command prompt select "run as administrator" command prompt will open C:\Windows\system32> type
takeown /f C:\windows

Type Exit press enter RESTART computer
northumbria - as I mentioned, P&P already running. FB - thanks - I'll try that when I have their computer here when they go to Mexico to watch whales (aright for some), so will be sometime before I report back.
