Ok...
Today i wanted to instal the new cura to print some harry potter glasses for my kid and it returned a similar error...
Needless to say there is more going on at this point
I'm almost ashamed to say i overlooked the fact that i run my desktop on my new NAS...
Because i often work in folders on my desktop to do quick stuff i have located it on the raid system which is safer than my system disk.
Since i wanted to install from my desktop it was actually trying to install from a network machine to my wks hence the security barrier.
The solution was to copy the installer to a disk that is 'in' my system et voila ..
/insert sad & dramatic violin music /
So thank you all (especially Elv) for helping me solve this, thinking with me and going the extra mile.
It didn't help that i was in the middle of a harsh deadline, otherwise i might have tried this sooner saving us all some sleepless nights.
MakeHuman is now residing on my main machine. *yay*
Cheers all.
