SmartSDR CAT will not open

New Flex 6500 installation with version 1.8.3 of SmartSDR and SmartSDR CAT on a Win 10 PC.  Maybe I did something out of order because SmartSDR runs OK but SmartSDR CAT refuses to open, either by clicking the icon or from the list of apps.  The task manager does not show the CAT program running.  Do I need to uninstall the CAT program (and VSP program?) and reinstall from the CD?  Tried "run as administrator" and that didn't work.

Thanks for any advice.    -- Bill, KA6T

So many people have had the dreaded lost cat syndrome. It appears one has to completely uninstall SmartSDR and reinstall. Completely uninstalling is a proverbial pain in the ass.

Also, 1.8.3 was withdrawn. You probably want to download 1.8.4.

        After updating to win 10 version 1607(?), I found that after re-installing SSDR I had
to run the SSDR installation one more time without uninstalling SSDR to get CAT on board.
It took running the SSDR installation program -twice- before the whole installation succeeded.
        My system may be quirky.  I've been in the windows 10 "insiders"  program from the
beginning, and some upgrades, especially the earliest ones, required extra effort to get
things right.  Many later versions went smoothly, not needing any particular attention.
This was the first time that I had to run it twice to get VSP/CAT to install.  The first time
through SSDR was installed.  The second time added CAT.  Good luck with this.  Windows
10 still has some "mysteries" associated with it, but you will get it going.  The 6500 will do
a fine job for you and it will be great fun.  Hang in there, and as Bob suggested, get 1.8.4.
