Hi,

 

When I try to open LaunchIW4M.exe, it crashes immediately without any error messages except the familiar Windows 7 "LaunchIW4M.exe has stopped working" with the following information provided:

 

Problem signature:
 Problem Event Name:	APPCRASH
 Application Name:	LaunchIW4M.exe
 Application Version:	0.0.0.0
 Application Timestamp:	4fbd2b4b

I also made a crash dump, you can download the file here (hope you are okay with zippyshare):

Some advice on what may cause the crash?

I have the same problem. The last time this happened was because of the master server, it was down. Might be the same.

people have been having trouble with iw5m too, but the muffin says the servers are up. so either the servers are down and muffin is lying, or every one just happened to all get the same error XD

 

 

EDIT: yep the np server is down

Hi and thanks for your responses,

 

As I understood reading other topics, the application freezes trying to connect to the server.

But for me, the launcher crashes immediately having caused a read access violation at address 0x0.

So I highly doubt it's even trying to connect to the server.

 

BTW, since when is the server down? I first experienced this issue yesterday at ~09:30 pm UTC.

i believe the server went down today...so then your error might not be caused by it

That's not a problem with the masterserver. A problem with the masterserver would cause an iw4m.dat crash, and what's crashing there is LaunchIW4M.exe

The fault module would seem to point to a .net Framework problem, but since you have windows 7 (wich has .net Framework 3.5 built-in) I decided to google a bit on your problem.

This is what I found:

Hope it helps you

Hi,

 

You're right, it looks like my .net Framework installation is damaged. I also noticed I can't install Windows updates anymore.

However, fortunately Microsoft provides some information+fixes for the error I get when trying to install those updates, so I'll first try that. If this fails, I'm afraid I have to reinstall Windows once again...

Anyway, thanks for your efforts

 

EDIT: I managed to get it working by doing an inplace upgrade of Windows 7 (some kind of reinstalling the system without touching installed third party software and data), which was the only working way to reinstall .net Framework 3.5.

Again, thanks for your help as you pointed me into the right direction.
