Assure that all installation files can be updated. Especially on Windows systems, a file that is still being used by a process cannot be replaced during the update. Therefore, you must assure that no program is still using any files or folders inside the ARIS installation directory.
Therefore, make sure that the following prerequisites are met:
All ACC commands are stopped
All ACC command-line prompts are closed
All Windows command-line prompts that access a folder inside the ARIS installation directory are closed.
All Windows Explorers that point to the ARIS installation folder are closed.
All files inside the ARIS installation directory that are not used by external programs, for example, log files opened by a text editor.
