Error: Installation failed for component Microsoft Visual Studio 2010 64bit Prerequisites
April 19, 2010 1 Comment
When trying to download Visual Studio 2010 RC, I ran the setup but the installer threw the following error
“VC 9.0 Runtime (x86) :  Error : Installation failed for component VC 9.o RUntime (x86). MSI returned error code 1603″
I removed all VC Components from the programs and features. Another error popped up
“Microsoft Visual Studio 2010 64bit Prerequisites (x64) :  Error: Installation failed for component Microsoft Visual Studio 2010 64bit Prerequisites (x64)”
After inspecting the error log i found the error in the .Net framework 4.0 machine.config i thought that error occurred because the installer did some action while installing the VC 9.0 Runtime and it was not rolled back in the machine.config . I removed all components installed by the Visual Studio 2010, started a clean installation and It worked just fine.
