CB installation location changes after auto update


I initially installed CB on my D: drive, which is a 1 TB WD Black drive and thus plenty of free space. The reason for me to choose my D: drive is
the fact that my C: drive is a 128 GB Plextor SSD which I keep as clean as possible thus various programs are NOT installed here(unless strictly necessary).
So it came as quite a surprise to me that CB, that has automatically self updated a few times, suddenly appeared to be installed/moved on my C: drive!!!
Do I have to uninstall CB and re-install on the D: drive and will the next auto update move the program back again??

CB version:
OS: Windows 7 Pro - 64 bit

You can create a folder shortcut “C:\Program Files\Comodo\Comodo Backup” which points to “D:\SomeFolder” . This should fix the problem for future updates.
