Off-topic - apologies in adv!: INF file issue..

[ChainsawJoe]

I apologise for the off-topic posting - the ActiveX forums are soooo quiet that I'm not expecting much of a response from there, and I really need anyone with one iota of knowledge about INF files, CAB files, dlls etc to help me out. I'm sorry I'm sorry I'm sorry! please forgive me and see if you can help figure this out!

I have a dead simple INF file within a signed CAB file which is supposed to register a dll on a user's pc.

Right-clicking the INF file and selecting "Install" on my local machine, yields success.

Putting the INF and the dll into a CAB file, signing it, putting it in a web page OBJECT tag, and browsing there - failure to register the dll.

After checking the "downloaded progs install failure log" thingy (using MS's "Code Down Load Log Viewer" - CDLLOGVW.exe), I find the error as:

*** Code Download Log entry (28 Apr 2004 @ 15:27:11) ***

Which is luverly.

Here's the abbrev. INF file

;--------------------------------------------------------------------------------------------------
[Version]
Signature = "$Chicago$"
;--------------------------------------------------------------------------------------------------
[DefaultInstall]
CopyFiles = LaunchInIE_CopyDll
RegisterDlls = LaunchInIE_RegisterDll
;--------------------------------------------------------------------------------------------------
[SourceDiskNames]
1 =, "Common Files",,
;--------------------------------------------------------------------------------------------------
[SourceDiskFiles]
LaunchInIE.dll = 1
;--------------------------------------------------------------------------------------------------
[DestinationDirs]
LaunchInIE_CopyDll = 11
;--------------------------------------------------------------------------------------------------
[LaunchInIE_CopyDll]
LaunchInIE.dll
;--------------------------------------------------------------------------------------------------
[LaunchInIE_RegisterDll]
11,,LaunchInIE.dll,1

Can anyone help me with this? Does the dll have to have been registered on the webserver in order for the CLSID to mean anything? I'll give that a go anyway..

Any help - PLEEEEZ!! I'm getting quite desperate to get this finished...!!
