Please QUIT and CLOSE any instances of Templot which are currently running.
S Mode
Firstly, it seems laptops supplied with
Windows Home are often set to
S Mode from new. You won't be able to install Templot, or much else, until you have escaped from
S Mode. The process for doing so is distinctly arcane, full explanation at:
https://windows.com/SmodeFAQ
Click
Windows 11 or
Windows 10 , and then
"how do I switch out of S mode?"
Then click this link to download the current version of Templot. The download will start after a few moments.
DO NOT click anything on the web page which appears, it is mostly advertising. The download will start automatically, even if I have been run over by a bus:
https://sourceforge.net/projects/opentemplot/files/templot_257a_setup.exe
Then open the downloaded file to install the current version. You do not need to uninstall any previous version.
