Hi there,

I try to extract the self-register information for a COM file written 
with VB6 a long time ago.

If I use regsvr32 to register the file manually on Win7 64-bit it works 
fine. But when I try to extract the information using heat with the 
following command line, just the file tag is generated, without having 
the com information extracted.
Command line:
        heat file file.dll -sfrag -srd -suid -svb6 -out file.wxi
Result:
        heat.exe : warning HEAT5150 : Could not harvest data from a
        file that was expected to be a SelfReg DLL: path\to\file.dll.
        If this file does not support SelfReg you can ignore this
        warning. Otherwise, this error detail may be helpful to
        diagnose the failure: Ein Aufrufziel hat einen Ausnahmefehler
        verursacht.

When I use Dependency Walker I can see, that a delay-load dependency to 
GPSVC.DLL was not found. That might be, because I am running a Windows 7 
64-bit machine, but the DLL is for a x86 architecture, but again: 
registering the file using regsvr32 works fine. I searched the internet 
and found an article [1] where the solution is to change the 
architecture of the dll to 64-bit, but that is no option to me.

So is there an other way to have the file self-registered during 
installation except using 2 custom actions to call regsvr32 and regsvr32 /u

Regards, Michel
