Hello, Since this morning I have really often a crashing Automation Studio on opening .st files. I have tried the following things, none of these options did fix the problem: Opened different ST files Removed the BR project and opened it again Upgraded AS to 6.5.1.17 Uninstalled AS6 completely a…

It seemed that AS crashed because of a corrupt component of the C++ Distribution. So we did the following to correct the issue: Removed both X64 and X86 versions of the 2015-2022 that are part of the AS installation addons. [image] Install the versions from the addon folder [image]

Hi @rene_pvh , Welcome to the community! I am sorry that you had some bad experiences with the latest AS version. Did you install AS 6.5.1.17 today or last week/s? Have you installed other sw or some windows upgrades after your AS installation? Are you using AS code too? I don’t that problem o…

Hi @valerio.manenti Thank you for the quick response. I have downloaded and installed 6.5.1.17 today. The last windows update was a few weeks ago and I have not installed any new software the last days. I normally don’t use AS code, today I have opened it a few times after I stumbled on the erro…

Hi @rene_pvh , not sure if my comment will help you, but I think about your note regarding “Building a project“ , I would like to share few notes made by my local Support in US focus on B&R Antivirus Exclusions: During the build process, AS needs write access to the following directories, which sh…

Hello Rene Can you see the source of the error in the Windows event logs? (Windows Event Viewer → Windows Logs → Application) If you create a new user with admin rights on the same PC, do you have the same problems with the new user? Jonas

Hello René, you wrote that building and opening a .st file triggers the crash. According to the crash report you’ve also build errors and warnings. Build: 1 error(s), 24 warning(s) Can you also check this points. Maybe it’s related. Best regards, Simon

Hi @rene_pvh , Are you working on “Compatibility Mode 6.3”? [image] New functions in ASW 6.0 If that the case could you try to convert the prj to AS 6.5 and see if you have the same issue? [image] Differences between working version 6.5 and 6.3 Ciao Valerio

Hello all, Thanks for all the replies. The event manager: I see the following application error: [image] The build warnings and errors: I have created an empty test project, without any warning or errors, after building is receive in the build, after building I am not able to open st files. …

Hi @rene_pvh , I asked AI help and below the answer: Exception code 0xc000041d represents STATUS_FATAL_USER_CALLBACK_EXCEPTION. It occurs when an unhandled exception is encountered during a user callback. While KERNELBASE.dll is often listed as the “faulting module,” it is typically a “victim” ra…

Hello, I have tried all these solutions, but it did not seem to fix anything. Only creating a new user profile is difficult in windows 11 without an office account. I have also uninstalled all br software (also older AS versions) and only installed AS6 again, but even this did not work. Best reg…

@rene_pvh I’m not sure what more we can do from Community point of view, you have done a lot, you have crash report, so I think it is time to provide all of these (including link to this discussion) to support team of your local B&R office. Maybe R&D team can read more from crash report.
