Can LTspice XVII and LTspice 24 Be Installed On the Same Win 10 Machine?
¿ªÔÆÌåÓýYes. Some people have even more versions on
the same computer.? XVII and 24 store their working files in
different places on your computer. Don't be tempted to make any
changes to files held within Program Files. On 2025-03-03 22:32, Jim wrote:

Hello Jim,
When you install 24, the installer will change all pointers in the registry.
After installation double-clicking any .asc, .asy, .net, .plt etc... will cause 24 to open.
?
Therefrom, the only way to use 17 will be to start it manually and throw your .asc, .asy, .net, .plt etc...? file onto it or use its open menu.
?
Also, I would make a copy of the 17 directory? from "Program Files" or where ever it is to somewhere safe in case Murphy's Law causes 24 to install on top of 17.
The copy of 17 can be put back anywhere if the original 17 gets clobbered by the 24 install.
Where ever 17 is stored it will run from there without issue by double-clicking the 17 .exe or via a shortcut to the 17 .exe.
17 will continue to use all the same library storage paths that it used to.
?
As for libraries, both 17 and 24 use "C:\Users\<user>\AppData\Local\LTspice\lib" to store the ADI supplied libraries.
Installing 24 will fully erase "C:\Users\<user>\AppData\Local\LTspice\lib" before installing all of ADI's latest stuff that comes with 24.
If you have your 3rd party library stuff also stored in "C:\Users\<user>\AppData\Local\LTspice\lib", as many have done in the past, make a copy of "C:\Users\<user>\AppData\Local\LTspice\lib" before installing 24.
You can sort out what models etc... you wish to keep and, where to store it going forward, after 24 is installed, because you made a complete copy of it.
?
All for now ?
