Hello,

I have a Hayes compatible modem driver .inf [COLOR=blue! important][COLOR=blue! important]file[/COLOR][/COLOR], which works fine for 32 bit windows7. We have a requirement to make the .inf compatible with windows 7 64 bit, for which the inf file was modified. the modifications are:

before
----------
[Manufacturer]
%M27% = M27

[M27]
%M2700% = M2700, PNPC031

after
--------
[Manufacturer]
%M27% = M27, ntamd64

[M27]
%M2700% = M2700, PNPC031

[M27.ntamd64]
%M2700% = M2700, PNPC031

However, after setting up the Dial-up connection, i get Error:777 The connection attempt failed because the modem (or other connecting device) on the remote computer is put of order.

The Driver details show that its refering to files:
C:\WINDOWS\system32\drivers\modem.sys and
C:\WINDOWS\system32\drivers\rootmdm.sys

I also tried adding modem driver from C:\Windows\inf\mdmhayes.inf
(the ntamd64 sections exists here too). The same Error 777 occurs.

Do I need to make any more changes in the .inf file ?

Hi.

You can't modify .inf files on Windows 64 bit and install, by default.

If you want to do that, you'll have to disable Driver Enforcement permanently, or upon each Windows boot from the the boot menu, so that the driver can load.

Further, you can't make a 32 bit driver work on 64 bit, no matter how much .inf edits you do. It doesn't work like that. You need a true 64 bit driver.

If you want me to find a signed driver for 64 bit that will work for you, right click it in the device manager. Properties. Details tab. Change the dropdown to hardware ids. Copy/paste the results to a new post here.

I don't have a modem, so I used my ethernet adapter as an example.
See how it has four separate line shown? I need all of them copied/pasted here.

If the pnpc031 is all that's there, it isn't going to be helpful.

Out of curiosity, could you perhaps post a screenshot of the device manager with the modem highlighted, that the pnpc031 showed up for?

I just want to make sure you're choosing the right one to get the info from.

This is the error I get when i select the .inf file before the editing( as mentioned above)

"The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for X64 based systems."

After editing, the system lets me add the modem driver without this error.
I have attached the picture of Details tab showing Hardware Id.

How do i find the hardware id/device id/vendor id, if this is not the right one?

When i go to All Programs > Accessories > System Tools > system Information and select Modem, the following details are shown:

...
Device ID ROOT\MODEM\0003
Device Type NULL Modem
Attached To COM1
...
Driver c:\windows\system32\drivers\modem.sys (6.1.7600.16385, 39.50 KB (40,44

Will this help?

Those are all Plug and Play devices, with drivers already installed.

"Radio Equipment Windows Direct Connection" was added by me, by manually selecting my .inf file.
