I have installed JRE 32 bits, then 64 bits
Then JDK 64 bits
I install my Eclipse and select d:\Eclipse as target.

I get this :

Fetching compositeContent.jar from http://download.eclipse.org/oomph/updates/milestone/latest/ (440B)

I closed the installer.
Went into Users\<myprofilename>
And there, I deleted the .p2 folder

Started the installer again : fails in standard mode
Also fails if I switch to advanced mode, with the same error.

Seems it downloads files, then it tries to "rename" and unless the log message is wrong, it seems to me it's trying not to rename, but move a file from a folder to another.

No idea how to fix this. Restarting the installer it always tries to use a .p2 folder inside c:\Users\<profile>

Yes, p2 downloads into the downloading folder first and then does a File.renameTo to "move" it to the cache folder (I assume to prevent partial or failed downloads from ending up in the cache proper). That apparently is failing, which is kind of inexplicable. However, from past experience, I've found that my virus scanner on Windows was the cause of this problem. I.e., it scans each newly created file and thereby locks it. Perhaps a virus scanner is involved in this problem.

I have been able to go around. I clicked on the small icon at the right of the "P2" line and selected a folder I created in my D: partition
Then, in the pop-up there was an alternative choice I used, and it installed perfectly

See: https://www.reddit.com/r/Windows10/comments/3iouzd/issue_windows_defender_locking_up_downloaded/

I disabled 'automatic sample submission', and the above error did not occur anymore.

I have windows 10, and disabled here:

Windows Defender Security Center
-> Virus & Threat protection
-> Virus & Threat protection settings

Adding -Djava.net.preferIPv4Stack=true to the end of the eclipse.ini file worked great The -vmargs parameter was already there.

Had this exact same problem on MacOS (High Sierra). I assumed this was a permissions issue since I was running the installer from my "Downloads" folder/directory. Moving the installer into the Applications folder and running it from there solved the problem for me.
