Cause

Oracle 12c Installer setup has Wrong value in file install/oraparam.ini for MSVCREDIST_LOC

From oraparam.ini

#MSVCREDIST_LOC flag will provide the name of the exe that is being shipped in stage/ext/bin
MSVCREDIST_LOC=vcredist_x64.exe

即Installer識別了錯誤的值，我們打開install/oraparam.ini這個文件可以看到MSVCREDIST_LOC=vcredist_x64.exe

實際上我們的文件是vcredist_x86.exe,所以導致了這個問題。

Solution

Installation of Oracle Net Configuration Assitant requires Microsoft C++ 2010 Redistributable (vcredist_x86.exe). If RTL is missing then Installation will fails with error message [INS-20802] Oracle Net Configuration Assitant failed"

Oracle 12C 32 bit client Installer should install the RTL automatically during the installation. However the oraparam.ini has wrong value for MSVCREDIST_LOC(Instead of vcredist_x86.exe) so installer fails to install RTL that is reason for installation of configuation Assitant to fail.

Follow the below instructions to resolve the issue.

1. Install Microsoft C++ 2010 Redistributable (vcredist_x86.exe) from the Installer location X:\client32\stage\ext\bin

意思就是先去軟件目錄:\client32\stage\ext\bin下安裝vcredist_x86.exe這個先。

2. Now click on retry

重新安裝就完美了。

Note : For avoiding the issue during the installation, edit the value for MSVCREDIST_LOC=vcredist_x86.exe in oraparam.ini

這裡也可以直接編輯MSVCREDIST_LOC=vcredist_x86.exe來避免。
