    Once you have downloaded the Eclipse archive you will need to decompress the zip file, which will create the unzipped Eclipse folder. You may want to extract the archive to the root of C:\ drive, thus creating the folder “C:\eclipse”, or just moved the extracted eclipse folder to the root of C:\ drive if you extracted it already. Since Eclipse does not have any installer, there will be a file inside the Eclipse folder named eclipse.exe ( ). You can double click on the file to run Eclipse.

    After eclipse has been fully installed and extracted, create a workspace folder where you will contain all the program files you create.

    Restarting your computer refreshes system memory and allows registration or configuration changes made by installers and uninstallers to take effect.

    I tried to install Eclipse several times but it keeps displaying "This app can't be run on your PC". What is going on?
    Community Answer
    Are you using Windows, Linux, or Mac? The main reason for such a display is because your system does not support the version of Eclipse you have downloaded. Also, check to see if your system is 32 bit or 64 bit.

    How do I create a html file?
    Community Answer
    Just make a basic Text file and call it "index", for example. Then rename it from "index.txt" to "index.html".

  • Question
    My Windows is 32-bit. Why can't I install JDK?
    Community Answer
    Make sure that the version of Java you are installing matches your computer. 32-bit computers should install the 32-bit (also referred to as x86) version.
