Slic3r wont open

I am sorry if this is the wrong area, I couldn't find where to put this topic.

I have been using Slic3r PE for a few weeks without issues, I love it. However, just a day or two ago, while I was using it, it randomly crashed. It's never done that for me before, but I thought no sweat, and tried to reopen it. It wouldn't open. It shows it opening in the processes tab for CTRL+Shift+esc, but then it disappears within a few seconds. I have tried completely deleting all the files and redownloading it all, restarting my computer, and installing the drivers for windows. I have a windows 10 machine. I am at a loss for what to do...

Re: Slic3r wont open

It took me about 3 tries on uninstalling and reinstalling it to get it to work again. I had to find all the files and delete them manually as uninstall did not remove all the files.

Re: Slic3r wont open

Hi I am having the same problem. The only time I can get it to open is when I do a fresh install, then it won't open again if I reboot my computer

Re: Slic3r wont open

Sorry to hear you are having issues with Slic3r. I would love to help, but we need more information.

If your crashes are caused by buggy Slic3r configuration, then it would help us, if you could please send us zipped content of you Slic3rPE data directory.

Also it is best to report the issues here:

Re: Slic3r wont open

I had the same issue. All problems started when I tried to slice a file with some errors. My computer got a bluescreen every time I tried to slice it. From what I read it was caused by outdated hardware drivers (eg. Watchdog timer and staff like this), so I updated them. After updating something like 15 drivers and restarted my pc Slic3r would never open again. When I try to open it only blink, and disappears. I reinstalled it twice but didn't help. Just to mention, every other program that i have works just fine after drivers update. Does anyone know what it may by caused by??

Re: Slic3r wont open

I hope this forum is still looked at, and the right place to post.

So I have just built up my i3 mk3 printer kit, everything works fine with it, have done a couple of trial prints from the included sd card. My issue is with the Slic3rPE software. It just won't open on my computer. When I try to open it nothing happens visually. If I have windows task manager open, I can see in the processes tab the name Slic3rPE for like a second when I try to open it, then it disappears from there.
I get no error messages, nothing.

I can open Prusa Control, but I want to use Slic3RPE because of all the extra options there. I am using Windows 8.1 64bit on a thinkpad T60, 2.3 ghz core 2 duo, 3gb ram. I know it's an old laptop, but I have no problems with most other things (for example I can run Solidworks 2015).

Anyone has any idea what to do? Should I try out an older version of this software?

I hope someone reads this too. My computer did a Windows 10 update last night.... Now Slic3r isn't loading here either. I tried reinstalling with no change. For some reason, I can't seem to roll back the Win10 update either. I've been using the Prusa version of Slic3r for several months without issues....until now. Any thoughts would be appreciated.

Re: Slic3r wont open

This worked for me:
https://shop.prusa3d.com/forum/general-discussion-announcements-and-releases-f61/slic3r-pe-1-40-won-t-open-t19726.html
Basically delete the files in User\AppData\Roaming\Slic3rPE\
But you will loose your custom settings

I didn't have such files on my computer, this is what I found:

C:\Program Files\Prusa3D\Slic3rPE\resources\profiles

I deleted the content of it, but it didn't help 🙁

Re: Slic3r wont open

I have had the same problem 3 times now. It will only work if I delete everything and reinstall.

So I've switched to a different slicer.

Re: Slic3r wont open

The AppData folder will need to be made visible, for those of you having trouble.

Use the directions found here: https://help.ableton.com/hc/en-us/articles/209070509-How-to-access-hidden-folders if you do not know how to do this.

Then follow the path: C:>Users>YOURUSERNAME>AppData>Roaming>Slic3r Delete the configuration file. It will be below the folders. When you open Slic3r again, a new config file will be created.

Thanks, I managed to follow that path now after I made that folder visible. Deleted the file. But the issue remained, Slic3r PE still didn't open. It just tried to load for a split second, then nothing. Upon checking the mentioned folder I see that it created a new configuration file.

At this point I have just given up on this software, and keep using PrusaControl. If my needs will require a more fully featured slicer program, then I will find something else.

Re: Slic3r wont open

Same for me, Slic3r Prusa Ed. crashed and would not open again, even after uninstall and re-install.

The above solution of deleting the appdata worked for me (appdata is a hidden folder, so be sure to make visible).

Thanks!
