I have downloaded LTSpiceXVII to my SSD first. Whenever I tried to choose a component at startup, it would first freeze and then crash. The same process has been happening after changing the file location to my hard drive. There is no error message.
Have you installed LTspice with all the default settings?
If yes, you should a have the folder below with th installed file.C:\Program Files\LTC\LTspiceXVII
When you then start XVIIx64.exe the first time, it will copy the library files and all example files into the user's folder.C:\Users\username\Documents\LTspiceXVII
Do you have the files in the two mentioned folders above?
In addition to Helmut's suggestions, yesterday LTspice was crashing for me too.
The issue resolved itself after I rebooted my laptop.
No, it still crashes.
Did not change any settings, the installation and library files are present in the Documents.
Maybe your PC has a problem with the RAM. Please run the WIN10 test program mdsched.
Close all programs.
Press the Windows-key and then enter mdsched in the search-field.
Now follow the instructions to let reboot the PC.
