Hiya folks - My issue is resolved & I found a way to resolve the problem with Alienware desktops/laptops that come pre-loaded with Alien Respawn. My CT8 now runs properly (& this fix seems to have also stopped the "in application" crashes I would sometimes experience with iC6 & CC).
Before I share though, it is
IMPERATIVE that you understand this fix only works for those machines that have the ORIGINAL preloaded version of Alien Respawn (It will NOT work if you have installed or reinstalled the Alien Respawn application yourself). I do not know if this will work on Dell Inspiron machines that come preloaded with Dell's Backup & Recovery as I do not have an Inspiron Machine here to test it on - but it worked on my Alienware Area 51 desktop & my Alienware MX-17 laptop perfectly.
That being said, this is what worked for my Alienware computers:
These steps must be followed EXACTLY to have the best of both worlds (Alien Respawn & CT8 on your machine with both apps working properly).
#1 - Download & install the current version iClone Product.
#2 - Once installed DO NOT LAUNCH - now create a Windows Restore Point (START > Create a restore point > Create button > enter a new name for the restore point file (I used POST CT8 Install & the date) > click create.
#3 - Using Control Panel > Programs > Uninstall Alienware Respawn
#4 - reboot machine after uninstall is complete.
#5 - restore system using the restore point you created in step #2
#6 - after system restores completely, reboot.
#7 - Launch CT8 & the Qt5.dll issue should be solved.
This corrected my issue with CT8 not launching/working - but PLEASE remember that this will only work on Alienware Desktops (like Area 51's) & Alienware Laptops (like MX17) where Alienware Respawn came preloaded on the machine. This fix does NOT work on machines where the user self-installed or reinstalled Respawn. Also I do not know if this will
work for machines with Dell Back Up & Recovery, as I have no Dell Inspiron or similar to test it on
