Question about Dell Inspiron 1420 Notebook
I cannot run any application, each time I open an application (.exe) a window appears telling me that "this is not a valid win32 application"
I tried opening my computer and the went to "tools", "folder options" and then in the "file types" section changed the file association for *.exe to application (%1) in the "registered file types" section but it still wont work. Then I tried changing the *.exe association to open with regedit32.exe just to see the difference and when I tried to open an application a window opened up saying "Would you like to add file.reg to the registry?"Yes"No". So I change the *.exe association back to application(%1) and then tried again but the the same window showed up.I still can't run any application.
My computer is Winxp PRO SP1
I have an updated antivirus scanner but it doesn't work since I had this problem.
Could you please help me get my computer back to normal again?
Often this error message will be similar to the below error message.
C:Program Filesmyprogramprogram.exe is not a valid Win32 application.
Cause: This issue can be caused by any of the below possibilities.
If the file or program you're attempting to run is corrupt or missing, Windows will be unable to execute the file properly and sometimes generate this error message.
If you downloaded this file and verified it is complete and compatible with your version of Windows, delete the file and try downloading and running it again. It's possible during the download that the file became corrupted.
Finally, if the second download does not work, try downloading the file from a different webpage. It is possible that the person or company maintaining the website mistakenly uploaded a corrupt version of the file you're attempting download.
Installing a program from a CD or other disk
If you're attempting to install a program and are getting this error, verify that the CD is clean. If the CD is dirty or bad, you could get this error during the install and/or get this error after the program has been installed because it was not copied properly onto the computer.
If you're running the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer you may get this error.
If the hard disk drive is corrupted or bad it can also cause working programs to fail either because not all the data can be read from the hard disk drive or because the program has become corrupted while on the drive. Run scandisk and defrag on the hard disk drive to check for any potential errors.
Long file name issue
Make sure the program or file you're attempting to run does not contain the same name as the long file name directory it is contained in. For example, executing a file named "program" in the "program files" directory can cause errors in some versions of Windows.
Additionally, if you're attempting to install a program and after the install the program does not work, you may also want to try installing the program in a different directory.
Any file can be changed or renamed to be a .exe file. If you're downloading the file, make sure the file is supposed to be a .exe file and that it's not being changed. If you're attempting to create a .exe, file make sure you're compiling the file for Windows and never just rename a file to a .exe file. For example, renaming a .bat file to a .exe file will not make the file an executable file. For a file to become an executable file it needs to either be compiled or converted through a software program designed to convert the file.
File is not designed for your version of Windows
If you're trying to run a program that is not designed for your version of Windows you may get this error. Although many older programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will work.
File is a virus, worm, or other malware file
This error can be generated by a file that is a virus, worm, trojan, or other type of malware file. Often, this will be caused because the virus scanner installed in the computer will not allow the file to be installed or run. Try scanning the file to verify it is not a virus and/or infected.
If the file has been checked and is clean, it is still possible that the virus protection program and/or another program installed on the computer is causing issues during the install or execution of the program. Boot the computer into Safe Mode and try running the program; booting the computer into Safe Mode will make sure nothing is running in the background that could be causing this issue. Additional information about Safe Mode can be found on document CHSAFE.
If you're getting this error during the installation of a program it's also possible that the CD-ROM drive or the drive you're installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
Download the latest drivers for your CD drive or other drive through our drivers page.

Tips for a great answer:
The process "winlogon.exe" runs in the background. Winlogon
Note: The winlogon.exe file is located in the folder C:\Windows\System32. In other cases, winlogon.exe is a virus, spyware, trojan or worm! Check this with Security Task Manager."
Winlogonis a part of the Windows Login subsystem, and is necessary for user authorization and Windows activation checks. http://www.neuber.com/taskmanager/proces...
Microsoft designed Windows so many small applications perform their tasks without a user knowing about it.
Normally, this will run smoothly and without flaw, but every once in a while, an issue can come up.
Winlogon.exe is an application that runs on start-up, and its primary function is to monitor the use of other applications.
Winlogon.exe typically only runs for about a minute or two when Windows first boots up, so if for some reason it is still running five or 10 minutes later, it could be infected.
Spyware and other malware would infect this application because it can manipulate other programs in Windows, causing problems.
If this is the case, the file might need to be removed.
if you want to remove this from
Open "My Computer" and select the "C:" drive.
Double click the "Windows" folder, then select "System 32." Navigate through the System 32 folder until you find "Winlogon.exe."
Click the "Winlogon.exe" file and hit "Delete." Select "Yes" when asked if you're sure you want to remove the program.
hope this helps
