Troubleshooting Upgrade Wizard Selection of Upgrade File

Overview

The Upgrade Wizard authenticates and downloads the upgrade file as expected, but does not allow the user to select the upgrade file to continue the upgrade.

Cause

One possible cause for this issue is the "upload_tmp_dir" parameter in php.ini referencing a directory the web server cannot read or write.

Resolution

To resolve this problem:

1. Open the php.ini file for editing.
2. Look for the following type of information:

      ; Temporary directory for HTTP uploaded files (will use system default if not
      ; specified).
      ; upload_tmp_dir = ""

3. Uncomment the "upload_tmp_dir" line and change it a directory to which the web server has read/write permissions.

      ; Temporary directory for HTTP uploaded files (will use system default if not specified).
   upload_tmp_dir = "C:Program Filesxampptmp"

4. Save the php.ini file.
5. Restart the webserver.
6. Restart the Upgrade Wizard.
