HDSDR on Win10: ExtIO, Load DLL failed #416

Closed hb9pae closed 7 years ago

hb9pae commented 7 years ago

Hi Pavel, I'm enjoying using the Red Pitaya with your excelent software, thank you for your effort! After new intstallation of my computer, HDSDR doaes not load the DLL "ExtIO_RedPitaya_TRX.DLL" anymore. (ExtIO, Load DLL failed), same behavior with SDR#.

I belive, that an older Version of the DLL worked well. Source of DLL: Red Pitaya notes > sdr-transceiver > https://www.dropbox.com/sh/5fy49wae6xwxa8a/AAABy8xWrv4wFFbkYfmVU6DGa/sdr/ExtIO_RedPitaya_TRX.dll?dl=1

MD5Hash of used ExtIO File: a96f9f84ddc6beb49796b509e7ea1f87

Thanks for any suggestion.

Hi Peter,

The current version of ExtIO_RedPitaya_TRX.dll was built in November 2015. Your MD5 sum is correct.

Could you check if Microsoft Visual C++ 2008 SP1 Redistributable Package is installed on your system? If it's not installed, could you try to download it from the following link and install it? https://www.microsoft.com/en-us/download/details.aspx?id=5582

Best regards,

Pavel

Microsoft Visual C++ 2008 SP1 Redistributable Package is installed, but same behavior. SDR# does not load the DLL as well.

Windows 10 (32 bit)

I tried HDSDR V 2.70 and the beta V 2.75, same negative result. (MSG: ExtIO, Load DLL failed)
Windows 10 Systemcheck SFC runs successful

On Windows 7, HDSDR loads DLL well.

The following two discussions mention a strange but working solution for the Microsoft Visual C++ 2008 and Windows 10 compatibility problem: https://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/error-error-997-while-installing-microsoft-visual/60a4f08e-a740-475d-8858-3435b2784b01 https://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/windows-10-will-not-install-visual-c-20082010/f7a5dadd-0ca0-4393-87c5-c44e9e305408

If I'm not mistaken, the idea is to the folder C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 to C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18_old and then to reinstall Microsoft Visual C++ 2008 and/or its redistributable package.

Hi Pavel, Thanks for the MS Support-Links. As I understand, the above Support-links covers about install problems with Microsoft Visual C++ 2008 Package. On my W10 System, I can install those packages without any problems.

Nevertheless I followed the procedure:

renamed the folder C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18
deinstalled the old Microsoft Visual C++ 2008 Package
reinstalled Microsoft Visual C++ 2008 Package newly

Starting HDSDR: ExtIO, Load DLL failed

I will do test with "Clean Windows Start" as mentioned in the Support-Note

I've rebuilt this ExtIO DLL using Visual Studio 2015.

hb9pae commented 7 years ago

Hi Pavel,

Using the new DLL (2015) HDSDR works great also on Win10!

Thanks so much for your support!

Hi Peter,

Thanks for the test. I've replaced the old ExtIO_RedPitaya_TRX.dll with the new DLL (2015).

Best regards,

Pavel
