How to download and install public hot-fix for TIBCO Statistica ?

Section 1 : Downloading the hotfix

Section 2: Installing the hotfix
1. Unzip all the zip file that was downloaded and all the zip files within that contains the executables.  Open the Readme file and carefully review the install instructions. For the purpose of this article, we can review installing V135HFS07 as per the instructions.

2. Shut down all instances of Statistica on the machine you are deploying the hotfix on. Users may want to open task manager as an Administrator and ask everyone currently using Statistica to close their instance or close the application with End Task.



3. If the machine where the hotfix is being applied is a WebStatistica/Livescore or MAS server, stop the corresponding Services by launching services.msc. 



4. Replacing executables as detailed in the Readme file. For the purpose of this example, we can walk through replacing the files related to V135HFS07. The installation instructions recommend that you take a backup of each file before replacing it. Since we have a number of files in this hotfix for the Statistica folder, the easiest way to deploy the hotfix is to simply make a copy of the entire Statistica installation directory and rename the copy to indicate it is pre-V135HFS07 (provided the machine has sufficient space to backup the entire directory. Then proceed to copy all the contents of the unzipped Statistica folder(with the exception of the Data Miner folder)  into the installation directory Statistica 13 folder (gif file attached for reference).



For the Data Miner folder within Statistica and the WebStatistica folder, since there is only one executable in the folder, we can do a manual rename of the executable and replace the file from the unzipped hotfix folder. Procedure detailed in gif below or referenced article : https://support.tibco.com/s/article/How-to-deploy-a-hot-fix-for-Statistica


5. Start the WebStatistica service, and the MAS Service if applicable
