To install the Service Pack you must have administrative privileges. By double-clicking the following link you open a download dialog box. The size of the download file is 38 Mb, so it is possible to choose ‘Run’, without saving the file to the disk. This installs the service pack. However, if you decide to choose ‘Save’ option, remember the folder where the file is downloaded. When the file download is finished, find the folder and double-click the saved file (RSA_RSAPRO_2009_SP1.exe). Service pack automatically recognizes whether your software is suitable to be updated.
