Bamboo 'Unable to open file' errors on Windows

Problem

Running a MettleCI Task in Bamboo results in an error message similar to

Unable to open file C:\Windows\system32\config\systemprofile\AppData\Local\Temp\mci9115423909078010390.auth.

The temporary directory (%temp%) for the current user is in a sub directory of the %windir%\System32 directory, usually caused by running Bamboo or a remote agent Service using the Local System account. When a 32bit Windows applications (ie. some DataStage clients) are executed on a 64bit Operating System, Windows will redirect the file system path from %windir%\System32 to %windir%\SysWOW64. This will prevent DataStage clients from accessing temporary files created by MettleCI.

Solution

This problem usually occurs when Bamboo or a Bamboo Remote Agent are running as a Windows Service using the Local System account.

There are two options for resolving this issue.

Option 1: Create a dedicated Windows Account and change the Bamboo or Bamboo Remote Agent services to run under that account as follows:

1. Locate the Bamboo Remote Agent in the Windows Services settings, right click and select “Properties”.
   
   

   Open

   

    

2. Click the “Log On” tab, Select “This account” and click the “Browse…” button.

   Open

   

    

3. Enter the username of that account you wish to use in the textbox and click “Check Names”

   If your username is not found after clicking “Check Names”, click the “Locations…” button and select “Entire Directory”.

4. Save changes and restart the Bamboo Remote Agent Service.

Option 2: Override Java’s temporary directory location to a directory that is not a sub directory of the %windir%\System32 directory:

1. Edit <bamboo agent directory>\conf\wrapper.conf where <bamboo agent directory> is the directory that your Bamboo remote agent was installed in.

2. Add wrapper.java.additional.3=-Djava.io.tmpdir=../temp after the line starting with wrapper.java.additional.2.

3. Save the file and restart the Bamboo Remote Agent Service.
