Normally I would not be asking for help with Windows XP, but I am trying to use Fiddler to capture the web traffic between a couple old appliances that require using ActiveX controls that only work on really old versions of internet explorer. I'm using Windows XP as a VM hosted by Oracle Virtual Box.
I've installed the .NET framework full profile version 4.0 and installed the 4.0.3 patch and all related patches from Microsoft Windows Update.
When I install Fiddler, it lets me install Fiddler version 4, so I know I've got the .NET prereq met.
When I launch Fiddler, I get an error from 'Microsoft Application Error Reporting' DW20.EXE and if I click details it reads:
AppName: fiddler.exe AppVer: 4.6.20171.26113 AppStamp:593ed566
ModName: clr.dll ModVer: 4.0.30319.2034 ModStamp:52ccfa2b
fDebug: 0 Offset: 00342980
There are two corresponding event's generated in the Event Log's application branch, which are:

Event ID: 1023
Application: Fiddler.exe

Description: The process was terminated due to an internal error in

I uninstalled Fiddler v4, selected to remove all registry settings, and then used 7Zip to unzip the installer, then installed Fiddler v2.
When I launch it, I get this error when I click on the details:

These are the Fiddler registry entries:

Is it odd that the "DetectedBrowser"="errorPID" in the registry?
IE launched after the install by the installer, but was blank. I could see two IE process IDs spawned by the Fiddler install, but they did not self close when the installer was finished installing Fiddler. I've got IE version 8 installed. I completely uninstalled IE8, returning me to IE6, and tried again with the same issue. I tried installing IE8 again, and also had the same issue.

I followed the recommendations at:
https://stackoverflow.com/questions/14056667/faulting-module-name-clr-dll-error-message-when-you-run-a-microsoft-net-fram/20028205#20028205
I installed the NDP40-KB2640103-x86.exe and the newer NDP40-KB2889629-x86.exe hotfixes for the .NET 4 Framework, but that didn't seem to change anything.
I also tried adding '<gcConcurrent enabled="false"/>' to the 'Fiddler.exe.config' file, but the crashing continues even with garbage collection disabled:
<runtime>
<generatePublisherEvidence enabled="false"/>
<gcConcurrent enabled="false"/>
</runtime>
I killed the 'Microsoft Application Error Reporting' DW20.EXE, so I could capture it's DMP files. I have two DMP files, one from when launching Fiddlerv4 and another from launching Fiddlerv2.
They are on my OneDrive and can be downloaded here:
https://1drv.ms/f/s!Au7APktuLWGumgk2WndQJzoVbMTM
The files are named:
Fiddlerv4CrashOnStartup.dmp
Fiddlerv2CrashOnStartup.dmp
Please let me know what further steps I can do to aid in resolving this issue.
Thank you,

Thanks for the detailed report. This is the first time we see anything like this.
The DetectedBrowser is irrelevant to this problem for sure. The .NET 4 as a prerequisite check is not a thorough check of the health of the .NET framework. It's more about detecting it's existence.
The .NET 2 version of Fiddler is final and has not been updated in quite a while. So in effect you tested two different versions of Fiddler. BOth of them exhibiting the same behavior makes me think there is something wrong with the machine where this happens. It is hard to say more though with the information I have.

I spent the day today building a brand new WinXPSP3 VM hosted on VirtualBox. I installed all the OS patches, but did not install any .NET Framework versions via Windows Update. I then manually installed dotNetFx40_Full_x86_x64.exe, rebooted, then installed Fiddler version 4.6.20171.26113. IE8 opens at the end of the install. I notice that there are three child IE processes spawned by the Fiddler installer. I close the IE window, but those child IE processes do not go terminate. I close the Fiddler installer and those three orphaned IE processes remain. I reboot, launch Fiddler and still fails to launch due to ModName: clr.dll.
Since this is a fresh install of XP and .NET 4.0, I can only assume that my VM's hardware configuration must be the problem. I switched my NIC from NAT to Bridged mode which didn't help. I'm wondering if I need to try a different VM setup within VirtualBox, such as using the ICH9 chipset instead of PIIX3, or enabling the I/O APIC option, or perhaps enable the virtual processor's PAE/NX checkbox. Should I change my NIC from the Intel PRO/1000 T Server (82543GC) to an older NIC like the PCnet-PI II(Am79C970A) or PCnet-FAST III (Am79C973)?
Certainly I can't be the only one who has tried running Fiddler under a VirtualBox VM. I haven't tried making an XP VM on a Hyper-V host yet to see if changing the host makes the difference. Perhaps that is the next step.
I just wanted to check to see if there are any known tricks or best practices to get Fiddler to work on XP using virtualized hardware. If Hyper-V doesn't work, then I've got an old desktop I can put a fresh install of XP on.
I also want to confirm that Fiddler version 4.6.20171.26113 should work with XP with .NET 4.0 installed, without any .NET 4.0 patches (like 4.0.3) or other .NET versions such as 3.5 or 2.0. I'm trying to confirm the minimum installation requirements. Does the XP OS need any configuration to make Fiddler work, such as disabling fast user switching, disabling the firewall etc.? Fiddler should work with IE8 right? Are there any tweaks I can do to Fiddler via the registry, or it's config file to enable tracing, or get it to start without everything enabled? Is there something I can do on the .NET framework side to enable better logging of the crash behavior? Is there a tweak that enables debug messages in Fiddler or .NET to send debug messages to a debugger like Sysinternals DebugView?
Today's crash's didn't generate DMP files, but it did make a TXT file that was in XML format, so I renamed it to XML and put it here:

I've succeeded running Fiddler 4.6.20171.26113 on Win XP SP2 with .NET 4.0 running on VM in VirtualBox. The chipset I've selected is PIIX3. The NIC shouldn't make any difference here. Both the I/O APIC and the PAE/NX are disabled.
Normally, there should be no OS configuration to make Fiddler work. It's just install and run. And yes, Fiddler should work with IE8 (I tried it even with IE6 and there was no problem there).
The only thing for debugging it that I can think of right now is to enable JIT debugging on startup, but this will require Visual Studio installed. You can find more information here.

Alexander
