".dll is either not designed to run on Windows or it contains an error." Help me fix this please.
I keep getting this "Bad Image" error, and it's interfering with my computer operation, slowing things down, and just being a general pain.
C:\Windows\system32\apphelp.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vender for support.
I don't think apphelp is the complete culprit, since this is a common (yet somehow unsolved, where ever I look) problem that occurs for a variety of different .dll files. (See
Please help, I just finished recovering my computer from a full factory reset, which I had to employ to get the non-functional computer to work again. I just finished reinstalling all of my software and updates for said software, only a few days ago, and
I really don't want to got through that again. I'm using vista home premium, 32 bit, service pack 2 I think, and I can provide any other information that is necessary.
• When do you receive the error message?
• Do you remember making any changes to the computer recently?
• Do you have any security software installed on the computer?
This error message might occur if there are some corrupt system files on the computer. Would suggest that you run a SFC scan which would scan for corrupt system files on the computer and replace them.
Steps to perform SFC scan:
1. Click the Start button
2. From the Start Menu, Click All programs followed by Accessories
3. In the Accessories menu, Right Click on the CommandPrompt option
4. From the drop down menu that appears, Click on the 'Run as administrator' option
5. If you have the User Account Control (UAC) enabled you will be asked for authorization prior to the command prompt opening. You may simply need to press the Continue button if you are the administrator or insert the administrator password etc.
6. In the Command Prompt window, type: sfc /scannow and then press Enter
7. A message will appear stating that 'the system scan will begin'
8. Be patient because the scan may take some time
9. If any files require replacing SFC will replace them. You may be asked to insert your Vista DVD for this process to continue
10. If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations"
11. After the scan has completed, Close the command prompt window restart the computer and check.
The scan may take some time, so be patient. Windows will repair any corrupted or missing files that it finds. If information from the installation CD is needed to repair the problem, you may be prompted to insert your Windows Vista.

If the above step fails I would suggest that you check if you have similar issue in the safe mode.

5. Select Safe Mode and press Enter.
6. You should see drivers loading, and then Please wait.
7. You should then be at the Welcome Screen.
8. Logon to your computer using an account with Administrator privileges.
