LTspice won't launch on Windows 11 - Core Ultra 7 255H, exits silently with no error

Hi MStokowski 

Thank for the reply, though despite doing exactly as you told it doesn't seem to work still.

I searched for ini files in the entire C drive and after a while 2 came back in results

I removed them and then did a fresh download and install but it doesn't not launch at all and similar behaviour in system as described in original question. 

Hi Fredrick ,

Hmmm. OK, let's get a verbose install log. Here's how, copy this in the command line, and change paths as appropriate:

msiexec /i "<Path to>\LTspice64.msi" /L*v "<Path to>\MyAppInstall.log

And we can go from there.

Once installed, see where it puts the LTspice.ini file. It should be in /appdata/roaming/ I believe.

 hello MStokowski 

yes found two .ini files directly in the Roaming root: LTspice.ini (9KB), LTspice_20260618_083042.ini (1KB). Attaching the verbose install log as well.LTspiceLog.txt

Hi Fredrick ,

OK, I'll look through the log. What previous versions of LTspice did you have installed, if any?

Hi MStokowski 

there was one updated on june 14th and then on june 17th 

i tried these two and none opened

therefore i downloaded ltspice xvii and currently on that only.

Hi Fredrick ,

New machine? 

mike

Yes, it's IdeaPad Pro 5.

Got in April of this year. 

Hi Fredrick ,

Thanks. Somewhat counterintuitive, but we do find most problems with LTspice installs are related to fact it is a new machine. Did you migrate anything from an old machine?

mike

Hi MStokowski 

No, i have not migrated any data at all.

It's a fresh install of windows right out of the box and whatever programs and softwares been installed on it are as i needed them by downloading from internet.

Thanks. I might have to go buy a machine to test… :-) 

Anyway, trying to track this one down.

LOL alright! 

Thanks, and ping me if you need further info.
