Recently explorer.exe has been crashing A LOT, usually 10 times every hour. Especially when using the start menu but also sometimes when nothing is running and when I'm not even at the computer.

The Windows Error Reporting Log shows that it is sfFavorites.dll which is quite odd since I didn't even know SmartFTP integrates into Windows.

Here is the log from 1 crash:

I downloaded the latest version 12 hours ago.

Please follow the instructions in my previous post.

Problem is still happening.

Post the crash information.

Sorry but the only crash log was the one I mentioned in the first post.

All other explorer.exe crashes print logs which are identical. (Apart from the time stamp)

Please post the log as requested.


I am sorry but I have no idea which log you're talking about.

The crash information which you can find in the Event Viewer.


The event viewer log is exactly the same as the first log which I posted, since the Error Reporting tool takes it from the event viewer.

Anyway here is the event viewer log:

Faulting application explorer.exe, version 6.0.6000.16549, time stamp 0x46d230c5, faulting module sfFavorites.dll, version, time stamp 0x475f31cf, exception code 0xc0000005, fault offset 0x000413a9, process id 0x14dc, application start time 0x01c841e5cdad3cf2.

Thank you.

Can you post the system information? You can find them in SmartFTP by going to the menu: Help->About "System Information"

Any news on the bug?

Hello ..

Open the command line (Start->Run. Enter cmd.exe). Then go to the SmartFTP program files folder:
cd "%ProgramFiles%\SmartFTP Client"
then unregister the shell extension
regsvr32.exe /u sfFavoritesShellExtension.dll
Then restart the computer



First time I unregistered it, I got a BSoD after restarting.

But after restarting a second time it seemed to go away. After unregistering it the start menu was much more responsive and I no longer get the error messages.

Thanks a lot for all your help!

Hello ..

I don't believe the BSOD is related to SmartFTP.

You can try to register the sfFavoritesShellExtension.dll again (regsvr32.exe sfFavoritesShellExtension.dll) as this dll is required for the Favorites window in SmartFTP. The dll - should - not get loaded if you don't start SmartFTP. Therefore it should not affect any context menus (Start menu etc).


Odd, because anything related to explorer.exe runs a lot faster now. Viewing files, starting up files, start menu navigation, system start up time. Everything is noticeable by a few seconds.
