[SOLVED] SFCFix crashing - Win10

[fireweed]

Hello, I'm trying to sort out some weirdness on my computer, but I am running into issues getting SFCFix to run. It was a decent way through the first time when it crashed. Now all the other times I run the program it crashes well reading cbs.log.

I've made sure my windows is updated, and I've ran SFC a few times and dism once after the first crash. Some system corruption was repaired, though SFCFix is still crashing. I've restarted my computer a few times, too.

CBS attached, and here is the link to the CrashDumps file.

Thanks for your help!

Hello fireweed,

The crashes all seem to be caused by msvcp80.dll which is a component of MS Visual Studio 2005. Please try temporarily uninstalling Visual Studio and see if it makes a difference.

Thank you for the advice! The machine is my surface from work and though I do work at an IT company and have permission to work on my machine to try and repair it, I need to check with our internal IT team to make sure I can uninstall it without messing with any of the programs they install on it. I will hopefully get permission from them and let you know how the uninstall and rescan goes.

Hello fireweed,

OK. I realise my previous post was very brief and I did not have much time to write up the analysis. I now realise you would probably appreciate more details so here goes.

I analysed the crash dumps you provided using WinDBG Preview (available from the Microsoft Store) and they were very similar. The main finding is the exception that was raised and which caused the crash.

At the time of the crash the stack showed the following was being executed - read from the bottom up to get the sequence of events.

To be honest I'm not entirely sure if this is a problem with SFCFix (which is a Sysnative tool) or to do with Visual Studio. I would need one of the developers to check this.

Thank you for the more in-depth reply, Phil. I wasn't sure the best program to download for viewing dumps so I'll definitely check it out.

I'd love to have spent a few hours on this at work but with the current focus on "billable" and "utilization" hours I don't really want to spend my whole work day on it. And of course I forgot my charger at work so I wanted to try and find a solution a bit faster. Researching some internal programs I cant see why any of them would need VS05 but hopefully I get the OK to remove it soon.

If you do check with the devs I'd be very curious to know the cause of the issue!

Hey Phil,

I have an update for you. I got the all good to try and get any VS2005 things off my machine but there were none in programs. I decided to see if I could temporarily remove the specific dlls and get the scan working but after fighting with trustedinstaller I got a prompt that our monitoring agent for remote access was using the dll, so I guess that explains that! I'll have to check on another work PC but if my hunch is right then SFCFix isnt compatible with the current version of the NCentral Windows Agent, which would kinda suck because I like the tool and would like to be able to use it on client machines if I need.

I'll check when I'm back in on Thursday.

I suspect you are right. You are possibly the first one to discover this anomaly. I'll make sure the developers see it. I'm sorry that it doesn't work but maybe we can still help by manually performing some of the fixes.

 

[fireweed]

I think that I may be alright for now? SFC is finally coming up clean after various scans and some dumb luck, I think. My webcam is working again and updates are completing. The computer even seems to be running better now, or as well as it can run as a dinky surface with 8GB RAM that I use at ~90% CPU and RAM usage all day.

I'll continue keeping an eye on it, unless you have any other recommendations for getting it working the best?

 

[philc43]

That does sound promising. If you are now up to date and the scans show no problems I think you are ok. Just keep an eye on it.

 

[fireweed]

Will do, thank you for your help with this!
