Description – When logging into a computer with the Logitech SetPoint software installed you receive an error that says, “Sorry, you must have Administrator privileges to complete this task.”

 

Solution – Prevent access to the update executable file.

1.     Browse to C:\Program Files\Logitech\SetPoint

2.     Right click LogitechUpdate.exe & select Properties.

3.     Select the Security tab.

4.     From here you have two options. You can either Deny the Users group Read & Execute or remove the Users group all-together.

Bad Image Error

March 12, 2009 1 comment

Description – When booting into Windows you receive an error that says, “lsass.exe – Bad Image. The application or DLL C:\WINDOWS\system32\MPR.dll is not a valid Windows image. Please check this against your installation diskette.”

Cause – This can happen if a chkdsk moves the file (and potentially others) referenced in the error.

Solution – Copy the files back to the hard drive from the Windows installation disk.

  1. Boot to the Windows XP disc. Make sure the disc is as close as possible to the version installed on the computer. (i.e. Use a Windows XP SP3 disc)
  2. When prompted press R to enter the Recovery Console.
  3. Select the Windows installation & type the administrator password.
  4. Look on the root of the C drive & navigate to the latest FOUND directory. In my case the directory was C:\found.000\dir0000.chk.
  5. Note the files that have been moved. There may be more than just the mpr.dll file in this example. In my case the files were mpr.dll, mprapi.dll & mprdim.dll.
  6. For each file, determine the directory that the file should be in. If there are multiple files, they could potentially belong in different directories. In my case, all three files are supposed to be in C:\Windows\System32. I also verified this by typing dir c:\windows\system32\mp*.dll. I noticed that those 3 files were there but that they all had a file size of 0.
  7. Copy each file from the Windows installation CD to the correct location. In this case the commands I ran were:
    copy d:\i386\mpr.dl_ c:\windows\system32\mpr.dll
    copy d:\i386\mprapi.dl_ c:\windows\system32\mprapi.dll
    copy d:\i386\mprdim.dl_ c:\windows\system32\mprdim.dll
  8. Reboot the computer. It should boot up like normal.
  9. For good measure you should run a chkdsk /r to make sure everything is OK. Using the /r switch can make it take a little while.

Allow Users to Change Power Options

To give normal users the ability to change the power settings, open regedit & browse to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg. Right click PowerCfg & select Properties. Give the Users group the following additional permissions:

  • Set value
  • Create Subkey

No reboot is needed.
