Problem Note 36701: Attempts to apply hot fixes fail with the error "No changes need to be made. Your system is up to date."
When the SAS® Download Manager copies certain files into the
SAS Software Depot folder,
the copies are incorrectly created with the date-and-time stamp that indicates when the
SAS Software Depot folder was created.
The SAS Download Manager does not preserve the time at which the files were copied.
Then, when these files are installed from the SAS Software Depot into the
they are installed with the newer date-and-time stamp.
The failure of the SAS Download Manager to preserve the original dates causes a problem when you
attempt to install a hot fix for the affected files.
If you attempt to install hot fixes that were released before the SAS Software Depot was created,
then the hot fix is not applied and the following message is returned:
No changes need to be made. Your system is up to date.
The hot fix installation fails because the date-and-time stamp on the file in the
SASHOME directory is more recent than the
date-and-time stamp on the file in the hot fix that the Maintenance Install Tool (MIT) is attempting to copy.
The file with the older date does not overwrite the file with the more recent date.
The following hot fixes are affected by this issue:
Base SAS® 9.21
SAS® Table Server Base Components 9.2
If you encounter this problem with the hot fixes listed above, use the
-alwaysoverwrite option to install the hot fix. To use this option, do the following:
Download and save the hot fix to the desktop of the machine to which you are applying the hot fix.
Select Start ► Run.
Click the Browse button, and select the Desktop icon from the gray vertical pane on the left side of the Browse dialog box.
From the list of files and folders that appear, select the name of the hot fix file
that you wish to install (for example, a01002wn.exe), and then click Open.
When you return to the Run dialog box, move your cursor to the end of the line and type -alwaysoverwrite
The command in the Run dialog box should look similar to the following:
"c:\documents and settings\desktop\a01002wn.exe" -alwaysoverwrite
Click OK to run, and then continue to follow the instructions on the MIT screens that appear for installing the hot fix.
If your system is running on the Windows Vista operating system, you must turn off User Access Control (UAC) or you will be unable to apply the hot fixes successfully.
To turn off UAC:
Select Start ► Control Panel ► User Accounts ► User Accounts.
Click Turn User Account Control on or off.
Deselect Use User Account Control (UAC) to help protect your computer and click OK.
