Hi,

On WXP 64
installation of x64 driver from 32-bit utility fails with error 0x4a020 .
This utility uses setupapi.lib functions and error code 0x4a020 is result of
function:

INetCfgClassSetup* -> Install(...)

Is possible to install x64 driver from 32-bit app on Windows 64, or what do
you recommend ?

Peter

Actually, 0x0004a020 is not an error, it is

#define NETCFG_S_REBOOT
MAKE_HRESULT(SEVERITY_SUCCESS, FACILITY_ITF, 0xA020)

and it means that you need to reboot in order for the changes to be
effective.

However, if I remember well, you need to use a 64bit application to install
a network driver on a 64bit machine (but I might be wrong).

Is the driver installed correctly after a reboot?

Have a nice day
GV

It is better to always do this way, not all important 64bit registry keys are
mirrored to the 32bit registry space.

Thank for answers,

installation with 32-bit utility was not successful even restart was done.
I built 64-bit utility for this and all is ok now.
