I just created an SDRSharp Test folder and did a fresh install using install.bat.
In the past, there were a few times that the nightly build was corrupted.
The one out there seems to be fine.
I've attached a list of all the files in that Test folder and SDRSharp runs just fine with them.
There have been times where users had a problem with version mismatched 'libusb' files.
If you check the date and size of all of the files in the attached list, then you should have a good installation and you'll have to look at other things.
The dates on many of the files will be the timestamp of when I downloaded them. For those you can verify the file sizes.
In my list of files, the only ones that should be different are the Config file and the Frequencies.xml file.
Those dates etc. are updated each time you run the software and I ran it just to ensure that it works.
