• Cannot open file because Windows needs to know what program created the file

  After downloading some files when I try to open the file, I get the message cannot open the file, windows needs to know what program created the file.

  Any suggestions?

  Perhaps no program has been assigned to this file format and so you cannot open these files.
  I put t know which files you downloaded, but you can choose an application installed that can open these files.

  Right click the file and I have to then choose open with.
  Then, you could choose the program you want to use.

  Best regards

  How to change or choose the program that starts when you double-click a file in Windows XP

• Cannot open files (desktop programs) *.exe

  When I try to open .exe files I get a message error that says "this file doesn't have a program associated with it for performing this action. Create an association in the Folder Options Control Panel. " I went to control panel > tools > folder options > file types and tried to put 'exe' to 'demand', but that doesn't seem to work. Funny enough, I am able to open other types of programs such as pictures, videos and files PDF and if I open a file html directly, I can open Firefox, but I can't open firefox.exe directly. I want to run an antivirus program or malware-check software, but of course, I can't open any .exe files.

  I am running Windows XP SP3 on a Lenovo Thinkpad T61.

  Hi Robert K B,.
   
  It seems that the file on your computer is corrupted, and the default program to open files is set to Adobe Reader.
   
  Method 1: As a first step of troubleshooting, you can uninstall Adobe Reader and check if the file associations are defined by default.
   
  Method 2:
  Once you uninstall Adobe on your computer, follow these steps to resolve the problem:
   

  a. Click Start, click Run, and type command

  b. type the following commands one by one:

  cd\windows
  Regedit

  c. If the Registry Editor opens successfully, then navigate to the following key:

  HKEY_CLASSES_ROOT \ exefile-shell-open-command

  d. double-click the (default) value in the right pane.

  e. delete the current value data, and then type:

  "%1" %*
  (ie., quote-percent-one-quote-space-percent-asterisk.)

  f. navigate to: HKEY_CLASSES_ROOT\.exe

  • In the right pane, set (default) exefile

  g. quit the registry editor.

  Check if this helps you.
