Hello. I am new to the forum and not sure if this is even the right place for my topic. I am not a computer genius, so if you can help, please try to explain things in detail (I don't know a lot about program codes, etc., but know about other things on the computer)

I am running Windows Vista with IE (not the new edition). I have noticed more problems with the computer lately, especially with Quickbooks Pro 2007 which we use for our small business. I have been having problems with it randomly shutting down and then not being able to open it back up unless I restart the computer. It hadn't been coming up with any codes, just a message saying it had a problem and if i wanted to hit "send" I could report the problem.

Yesterday, it randomly shut down on me and would not open back up (did not restart the computer). Came in this morning to use it (computer not restarted yet...sometimes it QB would open and work fine if the computer set for a little while) and it still wouldn't open. Restarted the computer and when I clicked to open QB up, it went to the "Loading Quickbooks" box like usual, then came up with this message:

Top of the box in blue says: QBW32.EXE - Unable to Locate Component
Body of box (starts with big red X like to close a window): "This application has failed to start because ACE.dll was not found. Re-installing the application may fix this problem.

If you click "OK" (only buttom that appears), a Microsoft Windows box appears that says
"Quickbooks has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solutions is available" Buttom that is present is Close Program.

Installed on the computer are Norton, Stopzilla, & Spy Bot Search & Destroy. I ran all of these and was able to get rid of a few problems (Norton came up with a Trojan). I also checked for updates on all of these programs and restarted the computer after everything was done.

I still have the same error message for QB (and computer seems slower now than before.....)

I did some reading online and found that this could be some type of spyware, but I am not sure as the best way to go about getting rid of it if it is. I REALLY need QB to work right now as I have some stuff that needs to be invoiced and such. Any help would be greatly appreciated.

ACE.dll is a legitimate Quickbooks file. It sounds like the program got corrupted. It is best to uninstall/reinstall the program
We can do a couple of scans to double check. If you use Spybot's Teatimer function, disable it for now


Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".


The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
