Hi there,

first time on here and i hope that you can help.
I have Windows XP with SP3.

I was running my usual clean up programs - ADsGone, Avast and Spybot.
I also ran in error a Canon printer exe update driver file that was used when i went to SP2.
I don't know if this caused my problem.

My problem is, i keep getting the error message:

Windows cannot access the specified device, path, or file. You may not have the appropriate permissios to access the item.

I'm getting this whenever i try any exe file OR anything in the control panel.

I've searched the web for 2 days now any nothing seems to help.

I can't even re-trying to add SP3 as it wont run the exe file. Even Start>run>regedit wont work.

any help or suggestions would be greatly appreciated.

thanks.

.exe fix

First we will need to create a version of notepad you can run.

Go to Start > Run and type in : CMD
In the command prompt type in (or copy and rightclick/paste):
COPY C:\Windows\notepad.exe C:\Windows\notepad.com

Please copy the entire contents of the codebox below into Notepad:
  • Open Notepad (go to Start>Run and type in notepad.com)
  • Copy the contents of the codebox below using CTRL+C (or selecting all the text in the box, and right clicking on it and selecting Copy)

  • Now return to Notepad and use CTRL + V (or rightclick on the whitespace and Paste) to paste the script
  • Verify that you have pasted the complete script
  • Save the Notepad file to your Desktop as FixReg.reg using Save as Type: All files
  • Locate FixReg.reg on your desktop
  • Double click to run, and when prompted Allow the file to merge with your registry
  • OK your way out.

After that, Reboot your machine


If this works, and you can now run .exe programs, Please follow the Malware Removal guide HERE. Post the logs you receive from the steps in that guide to create a new topic in the Malware Removal forum HERE

Did you get it fixed? Using command.com to create notepad.com and the registry fix?

Make sure and mention this thread in your new topic at the malware removal forum by posting a shortcut to it: ( you can right click, copy link location: http://www.geekstogo...le-t245278.html ) and paste.

Don't forget to mention all the problems you are having, including those with IE. If you cannot download the files needed in the removal guide on to that other computer, transfer them over using a USB Flash Drive.

The only other thing I can recommend is trying to do so in Safe-Mode. Though i doubt this will work.

This problem is most likely related to malware. For malware related problems, you will need to talk to the removal experts. I cannot help you further with this problem.

Please create a new thread HERE outlining your problem. You will receive a response there soon.

Hi again. I was thinking about your problem earlier.

Could you click on your Start button, right click on My Computer and go to properties?

Under the Advanced tab at the top, click on the "Environment Variables" button.

Under System Variables, do you see PATHTEXT listed, with
".COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH" as its data?

If you don't, try creating it using the above text as the data, without the quotes.

Also, should the person helping you in the malware removal forum not know what to do, how about you try Restoring your computer to an earlier date? This will hopefully reset your registry to a date before the registry was messed with to cause these problems.
