New Mac running High Sierra says "Parallels Desktop could not be started"

Parallels won't launch on my new MacBook Pro - even the installer won't launch, and now I have no Parallels Desktop installed (removed it trying to solve the problem) and unable to reinstall. Tried: Restarting (many), zap PRAM, download latest Parallels Desktop installer (several times), delete Parallels pref files and restart, disable SIP and try again (several times)... nothing seems to work. Can anyone help me please? ... ... Background: I bought a new MacBook Pro, I used Migration Assistant to transfer all my files, settings & applications from previous MBP (running Sierra) to new one (running High Sierra - latest update version). Parallels Desktop constantly refuses to launch saying "Parallels Desktop could not be started" in an error window with 'Please try again' and a small grey triangle with "Help me solve the problem" which opens to another line with link saying "Check this solution". Click the link and it takes me to a Parallels support page. Now, the phrase that accurately describes (the exact phrase in the error pane) the problem does not seem to appear on the page. It's become a HUGE problem for me, a week long rabbit hole of ineffective "support" (for the want of a more accurate term because support is SO difficult to get for Parallels -- they make themselves unavailable for support -- is that an economics thing? or just can't be bothered backing up their product?). Anyway, for a solid week now, I've been through an extensive list of attempts and repeated attempts and following links and trying this and that... anyway, no Parallels and no way to reinstall it. Just "Parallels Desktop could not be started." ... Any help much appreciated.

 

Thanks for the response Sathiya.
No success. No different to previous attempts. ... I completely uninstalled virus/security application, restarted Mac, checked that SIP is disabled using csrutil in Recovery disk, then did everything in the linked article, including downloading a fresh installer (the fourth I've downloaded in trying to resolve this issue!)... no success... again. ... When installing, the windows that come up, in order of appearance say: Click to install then (1) "Checking for new software..." (pauses here) then... (2) "Parallels Desktop requires an administrator name and password to begin installation" (I enter the info)... then it begins installing, then... (3) "Initializing Parallels Desktop..." then a couple of seconds, then (4) "Parallels Desktop could not be started".
Any more suggestions?
In case it helps: My OS= High Sierra 10.13.4 // Mac= MacBook Pro, 15-inch, 3.1 GHz, 16 GB 2133 MHz LPDDR3.
