[hpsdr] PowerSDR v. 1.19.3. on windows 7

[Tom McDermott]

The standard Windows error message about missing DLL can be kind of confusing. It really means:
 
1) Either the DLL is missing, or
2) The DLL was found, but something else that the DLL references can't be found.
 
Most likely the version of the DLL that you are trying to use was built referencing a C runtime library that is different (older) than the one installed on your system. There are some solutions:
 
1. Download Dependency Walker.  This is a free software tool that will search for all the dependencies an application uses, and identify which ones can't be found.  http://www.dependencywalker.com/
Open up the JanusAudio.dll in question and search for sub-dependencies.
There are a few false positives that you will need to ignore...
 
2a. Get the DLL source and rebuild it to use the most recent C runtime (or whatever else it may be referencing that is not on your computer).
 
or
 
2b. Identify the version of runtime library that the DLL needs, and install that on your computer.
