Hello, I am trying to uninstall QSPICE but I cannot find it neither in the control panel nor any uninstaller in its installation folder? I guess I am missing something here, any advice will be more than appreciated 
Go to “Apps & Features”, search or scroll for Qspice, click on Remove.
If you installed it in User mode, you have to manually uninstall it because User mode can’t register an uninstall method.
All you have to do is delete the top installation directory, typically C:\Users<your user name>\QSPICE.
If you want, you can delete the few registry entries it made. Search for “Marcus Aurelius Software LLC”
Your schematics, if you made any, will be in Documents\QSPICE. If you want to, delete those, too.

Hmm - that’s interesting…
Because on my Polish Win 10 64b Pro system in User (but with Admin privileges) mode it is definitely registered and perfectly start normal Uninstall procedure, which I just cancel…
I just tried to run Qspice, and was asked if I want to “uninstall” it, or cancel. It does not run…
How do I get around that?

QSPICE, being new, insists on running only a fairly recent build. You’ll have to update and/or reinstall. No need to uninstall first.
You can run the Program Update.exe which is typically installed in C:\Program Files\QSPICE.
We’ve since made the message you got more understandable.

QSpice gave me a new build that would not install at all when I tried it.
