Uninstaller doesn't (!), plus

[Duke Nukem]

Since installing the Elecard stuff (sorry can't be more specific, this area was beining investigated by a collegue who is off work) I've had problems playing back AVI files.

The typical symptom is the second or third time an application tries to load an AVI (without the app being closed in between) a GPF is generated.

When I run one of our own applications, in debug mode, I see two asserts failing in NTDLL, the call stack being :-

NTDLL! 7c901970()
NTDLL! 7c969588()
NTDLL! 7c96aea3()
NTDLL! 7c913fd3()
OLE32! 77a647e0()
OLEAUT32! 771254f4()
OLEAUT32! 771253c8()
EM4VD! 01f79833()

Once I traced the EM4VD to the Elecard things I ran the uninstall program. The problem persisted ! Typing the following at the command prompt :-

regsvr32 /u em4vd.ax

cured the problem !

So, 1) Why is em4vd causing a fault (I'm playing back DV AVI's which have nothing to do with the Elecard things ).
2) Why didn't the uninstaller fail to uninstall the em4vd.ax ?

TTFN,

Dear Duke,

Thanks for your questions. The problem with em4vd is known and it has already been fixed. The problem is related to auto rendering of em4vd.  

The fix will be provided in the next release of the decoder.

Duke,

About uninstall issue. Could you please describe it in more detail? What Elecard's programs have you installed on your system? Do you mean that the program uninstallation doesn't entail uninstallation of the MPEG-4 decoder from the system?

Appologies for the slow reply.

Unfortunately the chap looking after this is still off work.

However alls I can say is that there are ~40 files in the ProgramFiles\Common\Elecard directory, mostly .ax and .dll files.

The uninstall program did not uninstall these .ax files, I had to do them manually.

TTFN,

Duke,

The fact is that the operation system tracks the use of shared components. If some component has been installed by several programs, then uninstalling of one program doesn't entail the component deletion. It will be deleted when you have all the programs which share this file uninstalled.
