Open up Task Manager and confirm that there isn't an, "sa-mp.exe," process running. If it is somehow, then the installer won't be able to overwrite the file while it's running. End the process and retry the installation.
Also make sure your GTA:SA installation is the correct version. Download the downgrade patch and use it to either confirm that it's downgraded or to actually downgrade it. Once you've successfully done that, then apply a third-party patch, (NO-CD, etc.).
Make sure your antivirus is disabled and turned off completely before trying to install SA-MP again. If that allows you to install it without error, then allow exceptions for, "sa-mp.exe," before launching it after installation, just to be safe.
And yeah, this should be in Client Support probably.
