Hi! Are you running it from python?... The logs doesn't look like a one from the frozen app. Try to fully cleanup the library folder, it looks like a backwards compatibility issue.

[ArchitectMCP]

I am not running it from python. It's not a library specific issue. I cleared the library assignment, and created an empty library. The only change is a complete inability to even download a blender version, and recognize it has done so.

I have, at this point, cleared the registry of entries related to configuration, tried a new library, and (successfully) manually launched previously downloaded builds. Blender Launcher is the failure point and I have no idea what else can be removed or reset to get it working. It retains a memory of some kind that leads to it performing the exact same way regardless of being removed and reinstalled. It it's not the registry, and the library is starting from nothing, where else is the program squirreling data? AppData? Program Data? Registry keys outside the entries in Software?

[DotBow]

Please, provide a path to the library and show how it looks like inside right now.

[ArchitectMCP]

[DotBow]

Try to use a non system drive for library, it might be an UAC issue preventing for properly reading/writing data. Also, run a debug build to trace more info if the above solution will not work.

Closing because of inactivity

[ArchitectMCP]

I honestly forgot about this because the last response was so infuriating that I needed time away to avoid being rude.

To wit:

Library was always on system drive. No issues before this one. Still, moved library. No change. The log content provided WAS FROM THE DEBUG BUILD. It gives no information that the regular build doesn't also give.

Since that, have upgraded to 1.15. The only change is that the download_widgets.py error is now given as line 207 rather than line 211, and on restart it says the failed download is damaged. I used an empty library so I have no new information on its failing to launch. I have no reason to believe anything has changed since the basic issue remains.

At the risk of being repetitive, the issue appeared after an update to 1.14. Attempting to roll back to 1.13 did not remove the problem. obviously, 1.15 also creates the same issue.

So, I ask once again, where does the program keep its data on win64? Temp files, registry, appdata, etc. A complete list.

To be clear: Unless your request for further information is based on info I can't have because I didn't write the program and the information is not elsewhere on your git/documentation, I've already tried it. There was no further information. I provided everything there was to provide based on previously published troubleshooting documentation.

I do understand it's not reasonable to expect you to know that. Thus why I needed to take time to calm down. It's also why I'm telling you now. I don't need basic troubleshooting at this point. I am trying to perform the freshest possible install by removing all traces and any other settings that might be affecting the software.

It seems fairly trivial to say the problem is unique to my system. It's worth noting that there appears to be no difference between a Launcher download and a portable download of the same release. I'm currently preparing to do an inspection on the file content level to see if any differences exist.

[ArchitectMCP]

Addendum: Launcher believes build is damaged because rename fails. Rename fails because something in the process of generating the object info entry "subversion" fails.

It occurred to me that I hadn't done the obvious thing and parsed the code. I did that. Finding that the launcher wasn't working (in 1.15) because it expects a certain folder name format, I copied an old install from an old library. Blender Launcher was able to open this without issue.

Given the particulars of the python error, I believe the "self.build_info" object is not being created at all. Thus the NoneType.

It should be noted that I have a new error as of 1.15: 2022-06-25 09:45:19,123 - Windows - Blender Launcher 1.15.0 Traceback (most recent call last): File "C:\Home\Repositories\Blender-Launcher\source\widgets\library_widget.py", line 459, in remover_started AttributeError: 'QPushButton' object has no attribute '_setText'

This seems to be code to update the ui button "Delete" to "deleting..." while removing a damaged build. Can confirm that the button text does not change. However, this doesn't prevent BL from deleting the build. Will continue testing.

[DotBow]

HI! Sorry for a long response.

I will try to create a debug build for your case soon to trace an issue.

[DotBow]

Could you please reproduce an error step by step using Blender_Launcher_v1.15.0_Windows_x64_DEBUG.zip build?

Run it with following command from CMD "Blender Launcher.exe" -debug and send me a Blender Launcher.log file.

[ArchitectMCP]

Prepare for an anticlimax. Blender Launcher.log.

Hi! Thanks!

I think I found out the breaking point. Try to run build provided below (CMD "Blender Launcher.exe" -debug) and we will see what an actual error leads to the issue. https://drive.google.com/file/d/18rq65hr4vTFpqD-l2CFv0X7-wrUmbW75/view?usp=sharing

Hi! Thanks for report!

There is something wrong with the Blender process itself 🤔 Will be back with more info asap.

Could you please go to console and run following command: C:/Blender/daily/blender-3.3.0-beta+v33.b3fc8206be42-windows.amd64-release/blender.exe -v

[JoBilert]

I am not sure that we are talking about the same problem. My problem is, that Blender downloads but doesn't end the extraction process, and then cannot be launched from Blender Launcher.

If I call up the directory in my Explorer (Win11) and start the blender.exe it worked so far with any version I tried.

The message from the blender.exe -v was:

@JoBilert This is exactly what's happening. Getting build is more complicated than it seems. Following chain executes: download zip>extract zip>install template if necessary>read blender info>write blender info>rename folder>push build to the library UI Something goes wrong when BL tries to read info from blender. More specifically, the blender.exe itself fails to run. The only issue I can think of is permissions aka UAC. Need some time to figure out what else it can be.

[DotBow]

I added hook for getting output from blender process, maybe it will draw a light on the issue (same in CMD "Blender Launcher.exe" -debug)

Note: When run from terminal, these commands return no errors even when error message printing is forced.
