Win7 issue discussion #16
Comments
I have just noticed that Blender crashes when the process is called even without any arguments. So the problem is with calling Blender process itself. |
Found another problem, I called BRC by the console to test if rendering would still work. It did render chunks and mixdown like it should, but when came the time to join them, it got stuck on a loop where it the "Please select FFmpeg path" message popping up every few seconds. Once again, it seems it got messed up when calling ffmpeg to join them. (Using VirtualBox and Win7pro 32bit) |
have you tried debugging in Win7? |
there seems to be a pattern here: I have problems calling ffmpeg and you have a problem calling blender.. maybe it's some oddity about starting processes in Win7? |
are you trying that on 64-bit or 32-bit Win7? |
It may be some security issue... calling notepad.exe works. |
I'm using Win7pro 32bit |
Me too... still cant figure it out :-/ |
figured out my FFmpeg problem... I was using the 64bit FFmpeg on my 32bit system, whoops 🙄 So launching BRC from CMD does work, Blender never crashed in my tests, that's probably an issue in your end. still not sure about the Python issue... I installed VS on my VM and that doesn't show during debugging |
I tweaked the error detection when reading .blend info. Now it will only halt the operation and show a error if the get info process fails (StandardOutput = null). So Errors that don't interfere w/ that (like those plugin errors I've got) won't stop it.
Have you tried asking around stackoverflow.com or some site like that? |
IT'S IS A UAC SECURITY PROBLEM, turning off UAC makes it all work. |
Yep, but running the app as an Administrator does not make any change. Do you have any idea? |
I think the issue is the EXTERNAL processes we call (to get the .blend info for instance) don't get the necessary privilegies. I guess due to some Win7 issue they don't execute using the privilegies from the caller or the user, so even running as administrador won't work. |
I have tried to disable UAC in Win7 by setting that slider to "Never notify" and it still doesn't work... Are you sure that this made a change? |
Crap, I though I got it working, but i tested again and it didn't 💀 💀 Still, I believe the most likely cause is UAC. |
I made a .bat file to test get_project_info.py outside the program. It works in Windows 10, but only works in Windows 7 by running as administrator. |
runWin7.zip |
yea, for now that's the best thing to do. Later we can figure out a better way to make these calls work. |
I will try to figure it out tommorow when I meet my friend - an excellent programmer :) |
@lpslp Can you send the full message from the runWin7 error? Translated if possible? |
pic 1 error
pic 2 error
|
@lpslp thank you, btw is there a log.txt in the exe folder? If so send it too. |
no. program just freeze after press "close" |
@lpslp could you try to run this .bat? Post the results here place the bat in the scripts folder and run like this in CMD:
|
p.s. i probably know what you do say about my log but - take in mind - all my projects works and rendering inside blender it self - fine `Read prefs: C:\Users\xxx\AppData\Roaming\Blender Foundation\Blender\2.78\co
|
thank you, have you tried setting the output of your project to a folder? Try E:\project instead of the root E:\ |
tried change path to folder - same - freeze. |
@lpslp @Baldassarre I assume you guys are using the release version? Or have anyone tried compiling from the latest code? I've made a release of our latest code, see if the freeze @Baldassarre showed still persists. |
we go here but 0.8.2 do same - freeze
|
me and @jendabek have been made alot of progress in the past month, guess he forgot to update the release 🙄 that new error message means that does that happen when using runWin7.bat ? |
Great! It seems to work now! |
It works well (I hope for lpslp too), thanks beautiful job! |
So the running the program via runWin7.bat helped? |
Yes, it helped running the program via runWin7.bat. |
As of this post, BRC has problems opening projects in Win7. It's some sort of Python issue as far as I know
Fixing this is a priority!
Until that happens, a workaround is to launch BlenderRenderController.exe by the command line
