. Net installation in the episode-urgently needed solutions!

I don't know if you have noticed a problem ,. net installation is much more time-consuming than other software installation. General software installation can take up to half an hour, it only takes 45 minutes to install Windows (taking the time on my computer as an example. net takes more than one hour, or even half an hour. If this is the case, there will be more errors during installation than normal computers. I have a long history of installing software for my friends, but. I am still helpless with the installation of Net. He has too many requirements!
No, my computer system is faulty. I sent it to the after-sales service. After they helped me install the new system, the problem occurred. I mounted it to drive C. net was also formatted when the system was reinstalled, and my installation disk was borrowed by my classmates. It is estimated that it could not be returned within a month, but I had to download one from the Internet, that's the problem! First, an error will be reported when you start the installation map without the baseline database (what is that? I have never seen installation before !) Then he will run the installation interface, but when you installProgramAsk to restart the dialog box, and when you restart, the fault persists! I used to install a reboot on a friend of mine. net has also encountered a problem at that time, so I didn't go into any further research on the cause. Today I will share these issues with all the experts and look forward to your solutions! Thank you!
I'm in a hurry! Who !~~~~~~~
Note: I have checked my computer and it seems that there are no other. Net products!
