    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.

  • Application not found error-choose the program you want to use to open this file

    Soon all the world.

    I really hope that someone will post a reply to my question as soon as possible. I will try to be as descriptive as I could possibly, in order to solve my problems.

    The main problem is that I can't open some, if all the program files, applications on my windows 7, 32-bit laptop. I'm constantnly get application not found error, showing in a small window address, I was trying to do. Whenever I want to open a program, like the Adobe reader, word of microsoft, excel, mozilla firefox, google chrome - basically everthing, a window opens and is telling me this: choose the program you want to use to open this file: file: acad.exe... and recommend me acrobat from adobe program, any program I was trying to enter (in this case autoCAD).

    Cannot open cmd, when I go to system recovery, it says: System Restore could not start. I normally post records in: C and: D sheet music, play music, watch videos and see photos. I found a "hole" not being able to go to the internet via a browser. I discovered it when I went to an online help in some of the trobleshoots. It would open tab in google chrome by itself and then on it, I can browse the internet normally, but only through the said track.

    Currently, the microsoft security essentials performs a custom analysis (: C and: D), because I suspect it is a malware, or some kind of virus. It happened when I tried to download a program from CAD Solidworks 2012 via a site that I'm not sure I'm allowed to mention, that I don't want. Unless it's okay with you :) It begins with a letter t. By the way, I noticed that my: partition D has accumulated 10 GB + more in the space of a few days, because I remember two weeks ago I had close to 70 GB of free space, now it's about 56.3 GB. Curious, because I know that I did nothing so great in this period. Maybe I need to tell you that I get this window, from time to time, when I browse the internet (I never visit suspicious sites, or at least I don't me remember more I visited one in a very long time, like 4-5 months):

    2. What happens when you try to open the command prompt?
    3. What happens when you try to access the internet by using Internet Explorer?
    4. You did changes to the computer before the show?

    According to the description of problem errors you get "application not found error" and "choose the program you want to use to open this file" and not being is not able to do system restore, it seems that some windows file is corrupted. I also suggest you to post back the results of analysis.

    I would suggest trying the following methods and check if this is useful:

    Method 1:  Run SFC scan and check for corrupted Windows files and violations of integrity.

    Use the System File Checker tool to repair missing or corrupted system files

    http://support.Microsoft.com/kb/929833

    Method 2:

    For any question, where his prompting you to select the default program
    Try to set the default values for the program
    Change the programs that Windows uses by default

    For any question, where you are not able to download and install firefox, download the file and save it and then try to install firefox.

    I hope this helps. Please let us know the results. Feel free to write us again for any help.

  • BUG: Stop asking me what program I want to use it to open images in Windows 10

    Yes, there is another thread on this, but it has an accepted answer that does not solve the problem.

    In Windows 10 whenever you click on an image in Skype, you get an annoying screen asking what program you want to open it with. I have put my flaws so stop show and simply open the image.

    No, this isn't my file associations are not set up. I got them, I can double click on the images in the file Explorer and they just open, other programs can do that too.

    I even wrote a simple c# program

    Process.Start(@"IMG_03112015_100918.png");

    who has managed to open the image upwards with my associations - prove that Yes, you can do it programmatically.

    Windows changed how some API worked? Obviously. But you can bypass. It's something that should be fixed before Win10 went live. The fact that months later it is still a problem reflects really badly on Skype.

    Yes you did! Skype 7.14 works as it was intended!
