Well, it's not an installation fault, I reinstalled it again (4th time) but still was facing the same issue.  But I just downgrade my BIOS and again upgraded it and it solved the issue. I think Dell G7 7500 BIOS has some technical issue because when the BIOS v1.16 had come due to the dell power manager application cant able to identify the battery and BIOS v1.17 solved it but cause some issues in the SupportAssist application, not only that I perform it 2 more times to confirm that and still got the same result(By re-installing the windows again). So technically this issue was caused due to BIOS and downgrading the BIOS solved that issue. And now the application is working completely fine.
I have Dell G7 7500 (RTX 2060, 16 GB RAM), I clean install my windows 10 and updated it correctly but after installing everything from the dell support site(Drivers, BIOS, Application, etc) the Dell SupportAssist is showing unexpected error while running the drivers and update option same happing with the dell support site drivers and update option. Is it a server error or what?[IMAGE]dell application[IMAGE]dell site
