Question
.Net interop and "The specified module could not be found" HRESULT 0x8007007E
This is complex, but I'll try to explain completely & succinctly.
I have a VB6 application (call it App), using a .Net 3.5 assembly (call it Bridge) that calls other assemblies including a .Net 1.1 assembly written in VC++ (call it Worker).
Note that this configuration and installation set is working on multiple Windows XP and Server 2000 / 2003 systems. But I have one client terminal server that is giving me no end of grief.
When App tells Bridge to call Worker, Bridge throws the exception in the title. App duly logs it.
So ... I can talk to Bridge, but not to Worker.
Worker is in the same directory as App and Bridge. I've tried running Regasm on Worker -- to no avail. I've pulled Worker into the GAC -- to no avail.
Based on http://weblogs.asp.net/rch
I've rebooted with almost every change -- to no avail.
Versions of the Framework installed as reported by Control Panel are:
1.1
2.0 SP 1
3.0 SP 1
3.5
I let Windows Update apply Service Pack 1 for Framework 1.1 -- to no avail.
Ideas?
Thanks!

Strange, did you manage to get fuslogvw to log anything, the sucessfull loads for example?
did you find this blog entry? http://blogs.msdn.com/suzc
How does the VB6 app load and run 'Bridge'?
Also how does 'Bridge' attempt to run 'Worker'? Is it loaded dynamically or is there a direct reference?
Finally, sounds obvious, but how does the configuration on the failing client compare to the working ones - runtimes and patches installed etc.
yes, that blog entry was where I learned to use the tool -- since you recommended her blog.
App:
Dim B as new Bridge
B.SetupSystem()
Bridge:
Public Sub SetupSystem()
Dim W as Worker
W = new Worker
End Sub
>>Finally, sounds obvious, but how does the configuration on the failing client compare to the working ones - runtimes and patches installed etc.
Don't I wish I knew! Comparing to our "clean" test system ... Both have .Net frameworks 1.1 and 3.5. Both are XP SP2. On both Windows update reports that all patches are installed.
Not sure where to turn next ...
>>how does the configuration on the failing client compare to the working ones
We've found a possible lead we are pursuing.
The test system runs XP Pro, but its start menu claims it is running Terminal Server. One of the guys working on this for me says this is XP running in Terminal mode. He's trying to set our test system up on that configuration to attempt to replicate the problem.

Try using the Fusion binding log viewer - fuxlogvw.exe - http://msdn2.microsoft.com
Find it in your Visual Studio folder or .NET SDK folder -- SDK\v1.1\Bin or SDK\v2.0\Bin
You should be able to use it to see why the CLR loader can not find your module. Google Suzanne Cook's blog for lots of help with these kind of problems.
