Helix ALM Windows File Attachment Upload Error

Article ID: 337  |  Last updated: 26 Apr, 2017


An error occurs when uploading a file attachment in Helix ALM on Windows. The following error is returned when a record is saved with a new attachment:

'A communication error occurred during the transaction. Socket error caused incomplete request from []: File Transfer Error.'


This error generally occurs when Helix ALM has restricted access to the local Temp directory. The Temp directory is defined in the System > Environment settings.

Windows generally uses the following setting for the temp directory: %SystemRoot%Temp (e.g., C:\WindowsTemp). This directory probably has restrictive permission settings that do not give the Helix ALM read/write access.


Locate the Temp directory and change permissions to allow read/write access.


Specify an alternate Temp directory that has read/write privileges.
