Just tried to change the variable "TMP" to inside the mounted c:\users\ and then the 
install worked!

Same here. I have TMP and TEMP variables generally set to D:\Temp (joggling with low 
space on C:\ on this old laptop), and update has been failing until I've set 
environment variable TMP to the default "C:\Documents and Settings\MyUsername\Local 
Settings\Temp". 

After doing that, install went fine.

Sunand, Please replicate this.

I`m getting the same error when trying to update my 2.0.170.0 (11239) build to build 
located there - http://build.chromium.org/buildbot/snapshots/chromium-rel-
xp/11342/mini_installer.exe

chrome_installer.log is:

It is possible that an move optimization rahulk did does not work across volumes. 

Well if it's so, then it's an issue which is introduced in recent change commits. 
Until 2.0.168 upgrade it all worked well with same configuration.

I have more of a feeling that at one point install tries to use %TMP% or %TEMP% env 
variables, and then later on during upgrade tries to work with %USERPROFILE%\Local 
Settings\Temp or something similar and it doesn't find files there. So it fails with 
Error 7.

Happened the same tday with 2.0.169, fix was exactly the same (expected though).

Agree with Carlos. This looks like a p1. I can take a look. 

The underline implementation of move_tree is MoveFileEx. It seems MoveFileEx works 
for a single file across volumes but does not work for a directory across volumes. 
According to MSDN, the function simulates the move across volumes by using the 
CopyFile and DeleteFile functions.

(The moving across volume issue was discussed during code review, and Rahul mentioned 
it works across volumes. I'd assume it is tested with single file)

This is possibly the same  issue 8602 

 Issue 8602  has been merged into this issue.

This is a regression from r10921 to fix   issue 8218  .

Huan is working on a fix, and I'll patch up the release branch and re-release 169.

Revert the change in installer.cc to use MoveFile instead of CopyFile.

MoveFile fails across volumes, and many people have %TMP% on a different
volume than %LOCALAPPDATA%.

file_util::Move fails on Windows if moving a directory
across volumes. This change adds a
CopyAndDeleteDirectory function, and Move falls back
to CopyAndDeleteDirectory if moving directory fails.

r11460 should fix the issue. please verify.

2.0.170.0 (11460) was installed properly 
chrome_installer.log has zero size.

Where can I download the new version?????
