NWDS 2.0.13 Startup problem

Hello everyone !!

I have installed NWDS 2.0.13 on my PC. The installation was successful but when i run the NWDS it says Completing Install and then a pop up says <b>"Problems occured . Refer to the .log file in the .metadata dir of your workspace " .</b> As seen in another thread i also made an entry for the proxy address, but still getting the error. I then uninstalled and re-installed NWDS again, but the error still persists.

The .log file contains the following info.

    Hi,

    First Close your NWDS.

    1) Take a backup of your projects from the workspace and delete the .metadata folder from the workspace.

    2) Then open the NDS, a new .metadata folder will be created and now you can try opening the NWDS it will open without error

    3)Sometimes when your metadata of the NWDS is corrupted then your NWDS will not function properly.

    4)Restart ur machine,then its works properly

    Regards,

    Suresh

    Hi Melwyn,

    Before installing NWDS have you install "j2sdk1.4.2_06" ? During the installation

    have you given the proper jdk path??
