It if very hard to say the root cause of the issue without checking the
install log. But with MSDN troubleshooting experience you can try the below
1. Run the MS cleanup tool ; msicuu2.exe
2. After cleanup has completed.
3. Browse to folder c:\Windows and delete the Folder name Microsoft.Net
4. Browse to folder c:\windows\system32 look for a file name mscoree.dll and
see if it is available, and if you find that delete it
5. Click Start > Run > Type Regedit > Ok > HKEY_LOCAL_MACHINE > SOFTWARE >
MICROSOFT > Delete the key .Netframework
6. Rename the folder C:\MSOCache C:\MSOCache_old
6. Restart the computer
1. Click Start Run Type %temp% delete all the files there after you sort by
date modified and you might not able to delete some file which you can
2. Open a notepad and copy the as it is below and the save it as
Windows Registry Editor Version 5.00

4. This verbose logging will create the log file an will help MSDN to find
5. Run the installation of frame work. If it installs you are finished. If
not send the log files which will get created in the Temp folder with name
as MSI. Zip those files and send it to MSDN at;
