Hello,

I'm working on a new version of our product's company. I have a problem
where the new version, once installed, will simply not start. Apparently,
none of the .NET code is being executed either, because the first thing the
software does is open a log to document the startup process and that log is
never created. The application is Visual Basic .NET and it uses several COM
objects we designed. The same installer, when used on one of the dev
machines, produces a functionnal software.

I don't know much about .NET debugging, espicially when it occurs before my
code is even involved. I'm guessing is some missing dependency (although a
check with depends reveals nothing obvious).

If anyone could point me to tools or techniques to get more info on what's
going on it would be appreciated. Bugs like this, for us anyway, are usualy
caused by a missing or corrupted .NET framework install but I have
uninstalled and reinstalled and it doens't seem to help anything at all.

Here's what I get when I put the software in NTSD:

Show quoteHide quoteYou forgot to set a symbol path (without that, you're not going to be making
sense of any error traceback) but more importantly, you forgot to enter "g"
to start running in the first place. What you've shown here is just the
initial breakpoint of the application, which always happens....

Instead of breaking out the debugger, try something simpler first. Install
procmon (http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx) and
see if any obvious API calls fail. If that doesn't help, instead of using
NTSD, consider installing the Debugging Tools for Windows
(http://www.microsoft.com/whdc/devtools/debugging/default.mspx) which
contain more recent versions of the debuggers and, not unimportant,
documentation.

Thanks for your input Jereon,

I worked all day on this issue and still can't get a clue... I set the
symbol path and well, other than removing the warnings it didn't do
anything. As I said, it really looks like it's all happening before the
first line of code I actually wrote myself is executed... Looks like it's an
issue with a dependency, or .NET, or whatever.

I ran my process using procmon and I didn't get any new clues... I can see
where it's crashing, but none of the previous operations, success or not,
seem to give any indication of what's going on.

Here's the WINDBG output, after inputing 'g'. I'm hoping at least one of you
guys can see what I'm not seeing:

Yes, it is (specifically, "or whatever" is most likely).

[snip standard stuff]
Programs injecting libraries in every process, always good for a laugh.
Reboot in safe mode and see if that changes anything, you don't want stuff
like this possibly gumming up the works. The process should still work in
safe mode, but if it doesn't, you can use Autoruns
(http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx) to
selectively disable all non-standard startup entries. Or you can just
uninstall Web Creator Pro.

Web Creator Pro may not actually be the culprit. Take a hard look at
firewalls, virus scanners, low-level drivers and other stuff that likes to
install hooks and crash innocent programs.

You're this close to seeing where the exception is coming from. Enter

..loadby sos mscorwks [enter]
!pe -nested [enter]

And you'll get the details of the managed exception. I actually doubt it'll
be useful, though -- it looks like some very primitive assumption of the CLR
is being violated, so the exception might be something really low-level,
like "divison by zero". The location should still be of help.

Show quote Hide quote I will confirm later but I think I found the culprit. This new version was
compiled using Visual Studio 2008, as opposed to our last version which was
done using VS2003. The 2008 project defaulted to using .NET 3.5 and I didn't
have that one on the test computer. I'm having issues installing it for some
reason, so I can't confirm just yet, but I'm pretty sure that was the issue
all along.

BTW, MagicLibrary is actually a library we load on purpose, not one of those
borderline virus DLL :)

Thanks again for your input!!

Alex

Try something simple first like verifying that every dll your app needs is
on the machine.

Use depends on your exe to check this : http://www.dependencywalker.com/
