Once logged in, search for the official entry titled or search directly for the V11 Service Pack 2 trial files. Siemens typically hosts the trial as a series of downloadable split files (e.g., .exe and several .001 , .002 parts) that you extract together. System Requirements and Compatibility

If you are trying to open a TIA Portal V11 project in a newer version like V16 or V17, you cannot do it directly.
