I am not getting the where the problem is.I also tried eclipse 3.6 but the same problem is also occurring in that version.

Probably you had a local fail judging by this error. Try restart Eclipse and install this plugin again. But in general, to avoid such troubles, I would recommend you to install any Eclipse plugins manually from an archive file.

Unable to install Worklight for eclipse

I'm trying to install IBM MobileFirst Platform Studio in Eclipse Juno SR2.
But, each time I get the following error

I tried it initially in Mars. Even that didn't work.
Any idea why I get this error?
Eclipse Juno is not supported by MobileFirst Platform Foundation 7.1.
Use either Eclipse Kepler, Luna, or latest - Mars.
In Eclipse, go to Help -> Eclipse Marketplace and search for "mobilefirst", then install MobileFirst Studio.
Solved It !!
The problem was with my Network. It had a download limit of 150 MB, whereas, the plugin required around 250 MB. Once I removed the limit, there was no problem with the installation.

Installation of Helios' XML Editor into Helios based Eclipse fails

I am working with IBM Rational Function Tester 8.3, which is Eclipse 3.6 (Helios) based. I wanted to install XML support, so I enabled the Helios update site and chose Eclipse XML Editors and Tools 3.2.3 to install. I was promted for license agreement and then the installation started as expected. After some time downloading things Eclipse showed me an error.

No repository found containing: osgi.bundle,org.eclipse.core.resources,3.6.2.R36x_v20110628-1020
I also tried Eclipse XML Editors and Tools 3.2.2 with the same result. I verified that org.eclipse.core.resources_3.6.2.R36x_v20110628-1020 is in the plugins folder of the installation and that it is loaded in the plugin registry. The needed plugin is available and active.
I have no idea why this happens. Please someone can shed some light into this issue. What could cause this problem? Thank you.

The Force.com IDE isn't supported in Eclipse Indigo (3.7), so I wouldn't bother contacting support about it. You'll have to use an earlier version of Eclipse like Helios (3.6/3.5/3.4 are supported). Or just install the standalone Force.com IDE.
The messages seem pretty clear: the MD5 hash of the plugins you're trying to install don't match what they are supposed to be. It suggest that salesforce.com has a problem in their p2 repository - you should contact them about it through whatever support channel they provide.
I recommend Eclipse Helios (3.6) with force.com plugin

My solution: download plugin jar files manually and put them into eclipse installation directory. The problem was in corrupted (partial) download of jars by eclipse.
Download all jars of particular needed version from http://www.adnsandbox.com/tools/ide/install/features/ and http://www.adnsandbox.com/tools/ide/install/plugins/
Make sure to use some download manager to ensure files integrity!
Then put them to /features/ and /plugins/ folders of your eclipse installation directory accordingly.
Run plugin installation as described by salesforce (Jars will not be downloaded again) - Success!
Make sure you're running Eclipse as an Administrator (right click, select "Run as Administrator") when installing plugins.
If that doesn't help, move your Eclipse folder to the C:\ on Windows because there are issues with the Program Files folder permissions. Then run it as an Administrator and try to install the plugin again.
I just got it working;
Install Eclipse 3.6.1 (Helios SR1)
The IDE FAQ recommends Eclipse 3.5 and 3.6, but the install instructions link you to 3.6 SR1 .
Ensure you only have the latest JRE
I am running Java 6 Update 26 as of this post.
Make sure you don't have any legacy JREs installed
I had to uninstall a 1.4 Java environment before the IDE install would work.
Then follow what Matthew Keefe said;
Run Eclipse As Administrator
Move the Eclipse program directory outside of the Program Files directory.
Edit: Eclipse 3.7 installs the IDE successfully once the Java version is correct.

Read timed out
Have you tried the alternative installation procedure (from a zip file)?
Here is the work around :
Separately download the jar files for which read timeout is hapenning.
In this case download
com.google.gwt.eclipse.sdkbundle.2.0.3_2.0.3.v201002191036.jar.
com.google.appengine.eclipse.sdkbundle.1.3.3_1.3.3.v201004231111.jar.
using above url.
Note: both jars are above 80MB and takes a while for download.
copy the jars to plugin folder of eclipse
resume plugin installation once again.
