Could not open file .jar on my windows 7

Currently, I go to school online and we use Blackboard. I can't see or hear online presentations have .jar to the end of the file. Anyone know why? Can I use my old laptop with Vista and it works, but windows 7 does not work. Any suggestions?

Note: I should have mentioned that I have installed Java several times and had the Tech Help. All they can say is that there is a problem with my windows 7. I tried everything Basic. Anyone has any ideas that are not conventional? Thank you!

Hi Maggie,

The .jar files contain Java applications (jar means Java ARchive).  You need the Java runtime environment installed on your computer to be able to run Java applications.  It's not made or provided by Microsoft software.

http://en.wikipedia.org/wiki/JAR _(file_format)

I suspect there was an installation process, that you went through initially to use the Blackboard application on your system...  Your best bet is to go through this configuration once more on your Windows 7 system.

However, if you want to dive into the nitty gritty, the Java runtime environment can be installed directly from the Sun Microsystems website online:

    It would be probably the easiest, if not you will need to rename the three that are correct and also change all in the DescriptorFile disk and edit the .vmx file.  So the path of least resistance is to rename the real extent so 21 all have this form: "Windows XP Professional-s # hard."

  • The numbers "could not open file for some reason any."

    Suddenly some of my documents of numbers prompt response "numbers" could not open file for some reason any ' "the document is unavailable. Other documents numbers remain accessible. My backup versions invites the same response when I try to open them. Is there a solution?

    Hello Fred,.

    Thanks for this info and choosing the communities Support from Apple. I know how important is able to open all your files in numbers is for you!

    If I understand correctly, you cannot open some files of numbers even from backups, but others continue to work. To limit this problem, I would suggest starting with the following steps:

    1. first of all, run disk utility and check for questions on your hard drive, as hard drive problems can lead to situations like yours.

    Disk utility (Yosemite): a disc repair

    2. then, you can test this in a new user, to refine, if it's a question broad system or specific to your username.

    Thank you

    sandib5532,
    Try to use The Windows Installer Cleanup utility and see if it is able to remove your current version.  Alternatively, you can consult the Adobe removal instructions.

    @mrsimonrodriguez thanks for the tip. The correct answer is michaelarchbold to this thread:

    I had the same problem but I found if I copy the SDK to another location and all the symbolic links that disappears from the question of dereferencing.

  • Could not open file eps of Labview

    Hello

    I can not open eps file. I tried in Illustrator, Inkscape, rubber insert without success. The file is exported in Labview (see chart). I have 5 files and or it will not open. The file is located here.

    Thank you

    Comparing files in a text-editing program, the only difference I could see is that number 32 behind the polyline calls in 4 places. I removed the 32 and saved as .txt (plain text not RTF). I changed the extension to EPS and was able to open it with AICS5. Here's the graph

  • Could not open file .xls of recipients

    Sent by e-mail to several people with an .xlsb file attached. They are not able to open the file

    They must have a current version of Excel (Microsoft Office program), or a different worksheet, as LibreOffice calc or OpenOffice Calc.
    Not everyone has one of these programs, and they will not be able to open the file.
    For people who do not have a spreadsheet program mentioned, one option would be to export the file to PDF format. The recipient can then view, but not to manipulate the data.
