They are all simply runtimes and can be safely uninstalled. They are prerequisites and will be reinstalled when necessary or manually from Microsoft.com.
I hate to be like this but I have to put this out there... This computer seems to be acting erratically and it is causing you headaches and many work arounds. If this was me, I think I would cut my losses and reformat the computer. Sadly, it will probably take you less time to back up all personal data, reformat, reinstall windows with updates and reinstall programs than it will take to work your way around this. Besides, even if you do work around this I believe you still are dealing with a messed up and buggy computer.
I hate to say stuff like that because it sounds like a cop-out but sadly it is probably true and probably the most efficient way to get by this and end up with a good, solid computer. Just my opinion.
I also hate to agree with this but, after all, I must admit I can't act further ! And there's probably no doubt you are right.
I've tried to pass beside the difficulty but it seems that there is no hope !
I must admit the smallest allusion to this back up and re-install process give me an headache !
However, thank you all for your advices and help.
I was installing Autocad 2010 to my windows 7 laptop. I have also installed the microsoft.net framework 4 from this site
however, when i begin the installation process, a black screen just pops out and then gone. nothing happened. The installation didn't push through... what could be the problem of the installation process?
I have also turned off my antivirus.
Hope you could help me
I have not finished the install but ther gentleman in the prior post that gave the .net 4.0 d/l link was correct after you download and install the preceding .net 4.0 link then you do a Windows Update and there are six more files which have net 4.0 stuff in them and when that finishes I will reply back with another reponse and see if it installs correctly as well...
