LTspice XVII / IV Crashing everytime I try to run a simulation

[ZeTeX]

So, I've got LTspice XVII and LTspiceIV installed in my PC for some time, I used them daily and they worked great, recently I started using LTspice XVII more and it worked great.
but suddenly now, I downloaded an *.asc from the forum and tried to run a simulation and it didn't work, the software just "stopped responding" and crashed. I taught that the file is just broken so I tried opening an schematic that I made and it opened it great but again I tried to run a simulation and it crashed.
I've tried reinstalling LTspice XVII, didn't help or change any thing.
I've tried removing LTspiceXVII completely using "Revo Uninstaller" and then reinstalling LTspiceXVII but this also didn't fix the problem.
The same problem appears to be on LTspiceIV and LTspiceXVII.
How can I fix it?
Thanks.

Tedious but re-enter the schematic from scratch ? If its not throwing any errors
this and fixes you have already done just about the only choices.

Post the project and let someone else try to sim.....

it doesn't matter what file I ty, I tried creating a new schematic and I just connected a voltage source to a resistor and it still crashed when simulating.

There might be some configuration files not found be the uninstaller. LTspice is a little strange where it puts files when installed on newer windows versions (e.g. Win8.x). This caused a problem with automatic updates because of write protected directories - I don't know if it is solved in the meantime (I still use a older version because of this). 

I would try to locate the directories for configuration and similar files and another uninstall with a manual check that all old configs are gone. Also check in the directory where your circuits are - could be a bad config there too. There might also be something in the registery - though I don't know for sure.

Did the program hang and did you have to end it manually or did it just exit?
Did you install anything else that made it crash?
Have look in the windows application log if there is anything helpful.

Are you sure both LTSpice XVII and IV crash when loading that file?

I have had problems with XVII crashing, when trying to simulate certain circuits but never IV.

What version of XVII are you using 32-bit or 64-bit? I use the 64-bit version.

What operating system? So far it's only crash on Windows 7. It hasn't crashed yet under WINE in Linux, even though there are some minor bugs in the user interface which don't occur with Windows.

Try to get into the habit of saving schematics before running the simulation.

I don't know why it crashes. Missing files shouldn't cause it to crash. If it does because it can't find a file, then it's a bug. If the simulation fails because of a missing file LTSpice should abort the simulation and display and error, rather than crash.

That's why I have used "Revo Uninstaller", it's a software designed to remove any left registery or files that the LTspice Uninstaller left.

I click in start simulating, instantly the software freezes, then windows says that it has stopped responding.
No, I have not installed anything that made it crash, I just didn't use it for 2 days and today it happened on the first time opening LTspice.

Yep, the same problem in LTspiceIV and LTspiceXVII.
I've downloaded LTspice from here: http://ltspice.linear-tech.com/software/LTspiceXVII.exe not sure what version it is.
I'm using Windows 10.
it doesn't matter if I save the schematic or not.

I've noticed that the simulation sometimes work and sometime doesn't, 1 out of 3 times maybe the simulation will work and the software wont crash.

Do have a look in the application log in the event viewer:

Event viewer just tells me:

That tells you it's the 64-bit version.

Indeed, good thing my PC is 64-bit.
I have not restated my PC since the problem kept happening, I bet if I restart my PC now it will work fine.. will edit this comment if it helped.
EDIT: Restart did not help, but I've changed LTspice priority in task manager to "Real time" and it seems to helped, did not crash so far.

I too have had the problem that LTSpice keeps crashing (=not responding) when I run simulation - even after "complete" reinstall.
I just solved the problem by deleting all strange file from the default folder (where my .asc files live). Specifically, I deleted all .log, .raw, .plt.
HUGE relief - I really find the program invaluable.
Best wishes to others using the program.

Update - no, the problem's back - but I suspect there are other corpse files left by previous runs of the program that are causing this...
Sorry - I'll keep looking.

I have encountered this problem too, running on Windows 10 x64. What the hell?

Try the 32-bit version of LTSpice.

There a very good LTSpice group on Yahoo Groups.  A few of the members REALLY know LTSpice.

There are actually two groups, one is just a repository for models and examples.  The other is the daily chat group.
