Application Not Found...

Hey everyone. Let's see if you can help me with this. I have been trying for hours, but to no success.

I recently got a trojan from the much hated Windows Anti Virus Pro from a pop Ad that was clicked accidentally. I followed all of the steps to delete it and I thought I had, but now, whenever I try to open a file from my desktop I either get an "Application not Found", or a "Choose which file you want to use to open with.." message. I tried to go to the Start Menu to use regedit and all of that, but whatever this virus is has affected that too. When I try to use Start Menu Run, it says "Choose which file...". I don't know what to do? I can barely access any internet. Most files, I can find which file to use from a list of programs, like when I open Firefox, I just click Firefox, but for the windows applications, like Run, Control Menu, and Support Center I can't search for the program to use since I do not know which it is. Also, I have already tried System Restore and none of my Restore Points are functioning. Any ideas? Thanks in advance!

Those are what we call ASSOCIATIONS.
- Collapse -
Too tedious.

There's no way someone can re associate every file in their computer. This virus affects Every association.

That's why we have sites with fixes for such.

A Mr Doug Know has such a site.

--> But let me put this to you for a ponder. Wouldn't this be a good exercise for the person that maintains their own systems? Shouldn't they know how to fix associations and know what opens with what?

Sorry, that's Doug Knox.

The search still works to find it.

"Application not Found", or a "Choose which file you want"

I am having the same problem following Vundo Trojan infection. Re-associating the file applications does not solve this problem. It would take all day as you have to do it each and every time you open a document or application.

How did you get on

"Application not Found", or a "Choose which file you want"

I have Windows 7 not XP so I am not sure that this solution applies. I've found a work around which I am using while I takle the real problem -how to get rid of the Vundo Trojan that caused the problem in the first place. I'll let you know how that goes. I am going to try Vundofix and Vundobegone, then hijack this followed by Malwarebytes and Avg.

Associations apply to 7.

Same story, same fixes.

Re: Application Not Found...

jrank2889, I'm assuming you're using Windows XP.


Go to the link below and scroll down to line 12 (left column) and click on "EXE (lnk and regfile) Fix for Windows XP" to download a reg file fix. Save the REG File to your hard disk. Double click it or right click it and choose "merge" and answer yes to the import prompt.

http://www.kellys-korner-xp.com/xp_tweaks.htm

If you can't run the file do the following:

Press CTRL-ALT-DEL and open Task Manager. Once there, click File, then hold down the CTRL key and click New Task (Run). This will open a Command Prompt window. Enter REGEDIT.exe and press Enter. Once regedit is open click File>Import and locate that reg file fix, hilite it and click Open.

Note: If you can't access the Internet with the problem computer use another computer to download the reg file fix onto a CD, thumb drive, or floppy and transfer the file to the problem computer.

After that .reg file is merged into the registry successfully restart your computer.

Application not found

Hi,
I have a problem:
"I recently had some virus and I deleted them , but now, whenever I try to open a file from my desktop I either get an "Application not Found", or a "Choose which file you want to use to open with.." message.

You Might Want To Start Your Own Thread Or...

..it's also possible to manually edit the registry changes suggested. Download the .reg file mentioned in the earlier post by Tufenuf. Once downloaded, rename the file to .txt and open the document to see the specific registry edits the file would make.. Now open 'regedit' in Server 2003, and navigate to the registry items and manually make the changes IF they are required. Sometimes, there is no such registry entry in another operating system so it's not necessary to make a change.. On the other hand, if the registry items were corrupted or altered, then you could easily change them back.

Hope this helps.

What Is The EXACT Message You See? And...

..what types of files are showing the message? Does it happen only on desktop shortcuts which lead to programs? Or does it happen when you directly open a file, such as a Word document from your "My Documents" folder? Or maybe both?

Hope this helps and let us know more.

Hi Grif

Hi Grif,
Thank you for your note.When I want to open a file that I created in a program(for example I created a word document),it doesn't ask me to select user.But when I want to open microsoft office word for creating a file or ccleaner or visual studio or sql server or oracle or... from desktop or program files,it asks me to select users.

Application error......more issues

I have the same problem as jrank had....application not found. I know this is some kind of registry error because for example if I double click on say a word document the program opens to that document but if I try to just click on tnhe word icon to open it I get the application error message.

I cannot even open regedit. it does not give me an error...it just does nothing.

Anything i can do short of reload?

Same Answer...Tried The Solution In the Link Above?

No need to open the registry. Just download the file and run it per the instructions in the link.

Hope this helps.

Need some help

I was following what you said and went to the link but when I click on "12. EXE (lnk and regfile) Fix for Windows XP" it opens as text in a new window. I was going to try to add it manually but I am unable to open the registry editor, when typing either "REGEDIT.exe" or just "REGEDIT" into RUN it opens the list for me to select a program to open it with.

I realize the original post is a few months old but this is the only fix I have been able to find.

Thank you in advance.

Re: Need some help

Andrew, Did you try this with that reg file? Right click it and choose "Merge". If that doesn't work try this.

Press CTRL-ALT-DEL and open Task Manager. Once there, click File, then hold down the CTRL key and click New Task (Run). This will open a Command Prompt window. Enter REGEDIT.exe and press Enter. Once regedit is open click File>Import and locate that reg file fix, hilite it and click Open.

this fixed in windows 7 as well

Hi Tufenuf,

I had the simila issue in Windows 7 (due to same virus problem) and followed your steps and fixed the problem. But I am just wondering will it affect anything later due to Windows 7?

Thanks for your help.
