Hello,

Windows 7 64 bits does not accept driver that have not verified digital certificate.
So, when a driver has been developed by a no professional company, no money to give to Microsoft to get a certification.

this is the case of the driver we need to install : SAA7146A.SYS

I have found the solution : use DSEO (Driver Signature Enforcement Overrider)
you can find it here:
http://www.ngohq.com/?page=dseo
click on DOWNLOAD at the bottom of the page ( if you don't want to download anything you don't need).

you will go to a second page, go to the bottom and click <Agree>

dseo download2.jpg (172.62 Kio) Vu 59144 fois

now you have the file dseo13b.exe on your hard disk.
click right on this file and ask to "Run as administrator"

( sorry my win7 is in French so you will see some sentences in French...)

you will get the first DSEO panel :

dseo etape2.jpg (46.22 Kio) Vu 59144 fois

chose : "Enable Test Mode" and click Next.

dseo etape3.jpg (35.48 Kio) Vu 59144 fois

click OK an on the DSEO panel chose : "Sign a system file"

dseo etape4.jpg (45.36 Kio) Vu 59144 fois

DSEO ask you the complete address of your file starting from C:\...

dseo etape4 bis.jpg (31.11 Kio) Vu 59143 fois

we must find it, for that I go in the directory where it is : "Driver saa7146a 64-bit" and I must get the complete way to it.

I click right on it

< sorry for French sentences>

dseo etape5.jpg (104.36 Kio) Vu 59144 fois

ask at the bottom for proprietaries

dseo etape6bis.jpg (133.89 Kio) Vu 59144 fois

select with your mouse the complete address and copy it (CTRL+C)

go back to the DSEO question and put the address (CTRL+V).

dseo etape7.jpg (139.63 Kio) Vu 59144 fois

you will obtain an answer of success:

dseo etape8.jpg (35.96 Kio) Vu 59144 fois

Reboot your computer.

After reboot, you will see this announcement at right-bottom of windows screen

Now we can install the saaa7146A driver.

we cannot use the batch file to run the installation procedure. We must do it "by hand"
For that we will use the "Command Prompt" in Admistrator Mode
go to Start Menu > all programs, Accessories , right clicking Command Prompt and select "Run as Administrator"

we must write the whole sentence to install the driver using the "" characters :
"C:\ .... include full path \installdriver.exe" "C:\ ..include full path .. \SAA7146A.INF" "PCI\VEN_1131&DEV_7146"
on my computer I must write:
"C:\Users\cosinus\Tutioune 1600\Driver saa7146a 64-bit\InstallDriver.exe" "C:\Users\cosinus\Tutioune 1600\Driver saa7146a 64-bit\SAA7146A.INF" "PCI\VEN_1131&DEV_7146"
( I copied this sentence from my installSaa7146a.bat file)

dseo etape9.jpg (99.39 Kio) Vu 59144 fois

just after you execute this prompt, Windows open a panel to ask you to confirm to install this driver.

And now you can look at the Device Manager and see that SAA7144A driver is installed.

and if you run CheckMatosV3.0 you will find that all is OK, all LEDs are GREEN!!!

Good installation!

Merci Jean Pierre

I have tried most of your solution and will study it some more. I have since reinstalled a 32 bit version of Windows 7 and had no trouble getting the driver to install.

The rendering video problem was a motherboard vga issue and the wrong vga driver was installed. I have fixed that now and it is all up and working.

I will at a later date reinstall the 64 bit OS and follow your instructions.

Bonjour Jean Pierre,

Luca HB9FGJ in Féchy, Vaud (Suisse) here.

I am trying to install the SAA7146 driver in my Win7 32 bit installation but the installation fails with this message:



I have tried with the BDA driver, and the card (a TT S2-3200) works well with TT-Viewer.

Here is the Device Manager with the PCI IDs, which seem to be correct:



I have also tried with the DSOE trick (though I am on 32 bits) and even in test mode the driver cannot be loaded as, apparently, the card is not found by the driver installer.

Any idea on what might be the issue?

Merci et 73 de Luca HB9FGJ

[F6DZP]

You must un-install the BDA driver before install SAA7146a driver.
Installing driver under win7:

If we cannot use the batch file to run the installation procedure, We must do it "by hand"
For that we will use the "Command Prompt" in Admistrator Mode
go to Start Menu > all programs, Accessories , right clicking Command Prompt and select "Run as Administrator"

we must write the whole sentence to install the driver using the "" characters :
"C:\ .... include full path \installdriver.exe" "C:\ ..include full path .. \SAA7146A.INF" "PCI\VEN_1131&DEV_7146"

on my computer I must write:
"C:\Users\cosinus\Tutioune 1600\Driver saa7146a 64-bit\InstallDriver.exe" "C:\Users\cosinus\Tutioune 1600\Driver saa7146a 64-bit\SAA7146A.INF" "PCI\VEN_1131&DEV_7146"
( I copied this sentence from my installSaa7146a.bat file)

Dear Jean Pierre,

I have just upgraded my PC from Vista 32 Bit to W & 64 Bit on a new SSD rive. I can still dual-boot the PC. I have done everything above, but without success - I have a yellow ! triangle on the driver and the check driver application does not detect the card.

Any ideas?

PCI card detection
->No SAA7146A driver and/or card detected

[G8YTZ]

Oh,

my card is: "TechnoTrend TT budget S2-3200 DVB-S 2 PCI"

[F6DZP]

You can detect the card (S2-3200 or S2-1600) only after successful installation of SAA7146A driver.
I cannot say more about your Win7 upgraded from Vista. Perhaps there is a specific way to do it in this case?
Do you have Win7 in mode test? this is the first thing to obtain.

Tanks. Jean Pierre.
I have installed the driver,
but I think this card has a problem.

Verifmafos says:

and now only 2 checks are in red.

Thanks.

Hello,
Your card or your PC bus timing seems to have a problem.
Could you check if your card is well put in the PCI slot?
It seems they are data transfer issues, we cannot read at each time data coming from the card.

You could check also using Technotrend BDA driver and standard windows software.
