Eclipse IDE for Java Developers

Version: Helios Release
Build id: 20100617-1415

Windows 7 64 bit PC

I am using v3.6 32 bit because I need this version for a particular plugin.

When I attempt to Check for Updates from the Help menu I get the error below. I get the same error when I use Install New Software from the same menu.

What I have done so far is some searching and it seems the forums are suggesting to use JRE 1.6 to get around this bug. So, I have downloaded JRE 1.6 64 bit, changed my Java preferences to use this JRE, and I get the same error.

So then I think well maybe since I have the 32 bit version of Eclipse I should install JRE 1.6 32 bit into Program Files (x86) and change it to use that and I get the same error.

I'm new to this forum so I apologize if I have not found something that is already out there.

I was finally able to fix this by adding this line:


to the eclipse.ini file after -vmargs
