Eclipse won't start after uninstalling EGit plugin - eclipse

Question

I just uninstalled all of EGit plugins that I had before. The uninstall went through smoothly and asked me to restart Eclipse at the end but then Eclipse wouldn't start giving me the following error message:
I get that when I try to launch Eclipse from my shortcut on the Start Menu (using Win 7). But when I go to the Eclipse install directory itself and hit eclipse.exe there, I get the following error message:
I did go to see whether there is jvm.dll in the above directory and indeed it is there.
Any idea how to fix it?
UPDATE 1: I reinstalled both Eclipse AND JRE but the problem remains.
UPDATE 2: Here are the contents of my eclipse.ini
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502

Answer 1

JRE & Eclipse should both be the same bit version (32 or 64). Your screenshot suggests you're running the 32-bit version of JRE, but I don't know if that was before or after you re-installed. java -version should help with JRE. Your eclipse.ini file will tell you the Eclipse bit version you're running. For example:
plugins/org.eclipse.enter code hereequinox.launcher.win32.win32.x86_1.0.
You should confirm this and try manually pointing Eclipse to your JRE binary. Here's a Windows example
-vm c:\java\jdk\1.6\bin\javaw.exe
If that works, you just need to update your eclipse.ini with the correct path.
Good luck.

Answer 2

Turned out the Java I had (and the only version I had access to due to the corporate network restrictions) was 1.6 32-bit even though my laptop is 64-bit (why does this work?). When I tried to reinstall Eclipse, I was using the 64-bit version. It worked when I installed the 32-bit version. BTW, the Eclipse version is
