Spectrum Analyzer won’t run on Win10

Thanks Steve.

Your zip file only contained one file (Default.ini). I copied this as instructed and the analyser started up OK, but as you suspected it had a problem closing down.

I changed the folder permissions to allow Full Control for users and created an empty CurrentSettings.ini file but it still fails to close down.

The error window is attached and the full message is as follows.

Regards

Mike

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Hi Steve

I copied the files you sent to the SpecSettings folder and the analyser starts, but gives the same access error on closing.

If I try to save a screenshot while it’s running I get an unhandled exception error:

If I click Save Data, an empty folder called DataDump is created and the program closes.

Selecting Gains edit followed by Save As allows me to save the file to the Desktop, but when I tried clicking Save it created the GainTables folder then crashed when trying to write the file.

Running the program as Administrator doesn’t change the above behaviour.

Perhaps I should mention that my C: drive is reserved for Windows and programs while a physically separate D: drive contains all my data, including the Documents folder.

So the program can create the folders it needs under D:\\Documents\RSP Spectrum Analyser but cannot write to files in those folders.

Hi Steve

After much fiddling I have fixed the problem, which you will be delighted to hear was not of your program’s making.

It was my antivirus software (Bitdefender) which was preventing the program from “writing to a protected location”. Unfortunately it wasn’t alerting me to the fact!

Thanks for your support and thanks from me too for such a great program.

Mike
