is it possble to use LTspice without Installation with Windows 10?
LTspiceXVII is by default in this folder: "C:\Program Files\LTC\LTspiceXVII".
You can copy the program's folder from any installation to any other place and then run XVIIx64.exe from this new place.
First start of your copied version
LTspice will read the ini-file with your personal settings which can be viewed/changed in the Control Panel, e.g. color preferences. "C:\Users\username\AppData\Roaming\LTspiceXVII.ini"If this file doesn't exist, LTspiceXVII starts with defaults and it will create this file when you close the LTspiceXVII.
LTspiceXVII will also check whether the libraries and the examples are in the users's folder "Documents". If they are not there, LTspiceXVII will automatically create two folders with the models and examples."C:\Users\username\Documents\LTspiceXVII\lib""C:\Users\username\Documents\LTspiceXVII\examples"
Overall one can copy the files C:\Program Files\LTC\LTspiceXVII to any place and start LTspice from this place, but LTspice will create files in specific directories on the C-drive if they are not already there.
This brings up an additional question of my own. Above you point out that:
"Overall one can copy the files C:\Program Files\LTC\LTspiceXVII to any place and start LTspice from this place, but LTspice will create files in specific directories on the C-drive if they are not already there."
On one of my computers the C: drive is nearly filled to capacity. Is there a way to force LTSpice to use the D: drive in stead of creating files in specific directories on the C-drive if they are not already there?
It's not possible to use another folder for the model files copied into the user's Document-folder.
You can save space on the WIN-drive (typically C-drive), if you install LTspice on the D-drive. Then you will have only the models and the examples on the C-drive (40MB). If you are so limited with space, you should additionally change the path for Temp-files - C:\Users\username\AppData\Local\TempThis directory will be used when you directly open a schematic(.asc) on a web-page. This path can be changed in the Control panel -> Operation.
