Preparation
When installing Siemens software, you are often prompted to restart, and the prompt may still appear even after restarting, which can be inexplicably frustrating. Follow the steps below to delete the registry entry, and you will no longer be prompted to restart. Note: Do not restart after deleting the registry entry. Continue with the installation directly. (Deleting this file will have no effect on the computer.)
- In Windows, press the WIN+R key combination, enter “regedit,” and open Registry Editor.
Locate the PendingFileRemameOpeaations entry under HEEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\SESSION MANAGE\ and delete the entry directly. You do not need to restart; simply continue installing the software.

Notes before installation:
- V15 supports WIN11 WIN10 WIN8 WIN7, but they must all be 64-bit systems.
- Once the files have finished downloading, if an error occurs during installation, reinstall or repair the software. If the problem still occurs when you install it again, you can only reinstall the operating system and then install the software again. This problem occurs because TIA Portal is a large software package, the database files it uses are very complex, and other third-party software on the system may prevent TIA Portal from installing successfully. Therefore, keep the system as clean as possible before installation. Remember: under no circumstances should you start any antivirus software, especially 360. Otherwise, there is no guarantee that the installation will succeed or that the software will work properly after installation.
Be sure to close all antivirus software before installation

④ Licensing
- Find Sim_EKB_Install_2018_11_14.exe in the licensing folder, right-click it, and select Run as administrator.

If the software is not successfully licensed after restarting, find and delete the AX NF ZZ folder on the C drive. (If you cannot find it, enable the display of hidden folders.)
If licensing still fails after you complete the steps above, you need to reinstall a clean Windows system. Do not install any other software, antivirus software, system management tools, or similar programs; install TIA Portal directly.
Find TIA Portal V15 on the desktop and double-click it. The software should start normally.
