Hi, I cannot setup some program successful.

Last month I setup the same program in my laptop, that is Windows 8.1, all programs setup were successful.

But now I switch to the desktop,  Windows 7 Ultimate, and it has some problem.

The Photoshop CC; Illustrator CC; After Effects CC and Media Encoder CC shows it was fail to setup, because it says Exit Code: 6 Please see specific errors below for troubleshooting.

ERROR:

0 fatal error(s), 2 error(s)

Please try installing it by double clicking on the executable at "C:\Users\YZY\AppData\Local\Temp\{8CE27FEA-F049-477B-9224-4A0718E77DE6}\Photoshop_15_LS20_win64\Adobe CC 2014\payloads\Microsoft VC 2008 Redist (x86)\vcredist_x86.exe", or download and install the latest Microsoft Visual C   2008 Redistributable Package (x86) from Microsoft website - www.microsoft.com

It seems that has some problem about Microsoft Visual C++ 2008 Redistributable Package (x86); then I download this from microsoft.com, and I retry it. But it still fail to setup. Then I find the place where the program setup, the program can run successful, I'm confused is this program setup successful?
