SmartSDR CAT requires the FlexRadio Systems FlexVSP driver to be installed. Please reinstall SmartSDR to install this driver.

Yet again, I find myself unable to use SmartSDR.  I needed to connect a Yaesu data cable to one of my USB sockets and it 'self-allocated' COM4 which is, of course, one of the non-changeable COM ports which SmartSDR uses.

I manually remapped the Yaesu cable to COM9 (the next available one) and it is working fine. The other COM ports (COM3 = IC-7300 / COM6 & COM7 = IC-9100 / COM8 = BlueDV) are all working properly.

SmartSDR CAT however is not.  I have this issue EVERY SINGLE TIME I need to create a new virtual COM port from USB (it last happened just a week ago).

As I always do, I followed Tim's procedure to completely remove SmartSDR and all its components.  I  also removed the ghost (hidden) COM ports, deleted all directories etc. and rebooted.  

I then re-installed SmartSDR v1.9.13 and rebooted.

I then got the message "SmartSDR CAT requires the FlexRadio Systems FlexVSP driver to be installed.  Please reinstall SmartSDR to install this driver."  

I went to c:\Program Files\FlexRadio Systems\SmartSDR v1.9.13\64-bit Drivers\VSP and executed FlexVSPInstaller_64 which appeared to run without errors.  I then rebooted.  I have the same issue.

I repeated the whole procedure two more times (this has taken me ALL DAY) and I still have the same problem.  

I repeated the entire procedure yet again and also purchased Revo Uninstaller to assist in deleting registry entries etc. Which may have been missed. I still have the same problem.  

I do not know what to do next apart from unplugging all my FlexRadio Systems equipment, putting it back into its boxes and either selling it or waiting for a fix whereby we can start the SmartSDR CAT ports from a starting point of our choosing other than COM4! I will very soon need to add a further device which is my rotator controller interface and I cannot face going through all this grief every time!  I want to get on the air not fiddle about with COM ports!

To say that I am finding this frustrating would be an under-statement.  I hope that I shall be able to mention it to Gerald at the weekend when I attend the RSGB Convention.  I really need to make sure that FRS understand that many of us use multiple COM ports and we MUST be able to allocate them ourselves!

In summary, if anyone else if having these problems.  Check that the Windows Installer service is running before starting the SmartSDR installation.  
That was the solution to my issues although I do not know the route cause - perhaps the SMartSDR installer was not trying to start it OR not aborting when it would not start.  I do not know!
