Everytime I try to install this update Microsoft .NET Framework 3.5 Service
Pack 1 and .NET Framework 3.5 Family Update (KB951847) x86 I keep getting
error.
Code 643 I went to numberous help pages and done everything they said to do
to try to fix this but it still refuses to fix. I used the
dotnetfx_cleanup_tool to uninstall every version I had on my machine and when
I downloaded the latest version and install it I get the same error
everytime. I've exalted every option that is out there
and I belive there no way that this issue can be fixed. This is my log file.
