SoapySDR DLL Doesn't Load on Windows 10

[gstrike]

Hello,

I'm running SDR++ v1.0.3 on Windows 10. I am attempting to utilize my hackrf, which is available on the network from an Ubuntu machine running SoapySDR / SoapySDRServer.

It appears the soapy_source.dll doesn't load when launching SDR++ with:

[error] Couldn't load ./modules/soapy_source.dll. Error code: 126

I'm not sure if this is a bug or something I'm missing.

I've done some scouring to see if I'm missing something and found some references that made it look like PothosSDR may need to be installed, which I've done, but it didn't help.

You need to have SoapySDR installed on your system. It can't be shipped with SDR++.

Install PothosSDR and make sure to check the "Add to path" option in the installer

Thank you for the reply. I did do that prior to my post (including the Add to Path)...

It is working now... I needed to close/re-open the Command Prompt window... Ugh.

Thanks again.

For those looking in the future, the latest Windows installer for SoapySDR can be found here: https://downloads.myriadrf.org/builds/PothosSDR/
