[NS-30131] Initial setup required for the execution of installer validations failed

Error:
I am running setup.exe to install Oracle database software binaries but once the GUI opens it shows error.
[NS-30131] Initial setup required for the execution of installer validations failed.

Cause
1. Software Corruption
2. On Windows, Check USER having access to temporary TEMP and \\localhost\C$ access
3. Check if Windows services “OracleRemExecService” is running due to client already installed.
4. You can ignore OSCheck option if upper 3 not work.

Solution

1. Software Corruption
For check the Software integrity by following link:
Verify the Software Integrity

2. On windows, check user permission to TEMP and \\LOCALHOST\C$ access from RUN command
If permission is not present then give permission and try installation

--Give permission of TEMP folder in windows and Try to open from RUN window:
RUN --> \\\c$

OR
--Open CMD windows with Administrative right and change the TEMP path where user has permission temporary in CMD as shown:
SET TEMP=E:\TEMP
--Start the setup from CMD windows by going to software location and run setup.exe
E:\Software\Oracle12c> setup.exe

3. Check if Windows services “OracleRemExecService” is running.

In Windows if you install Oracle Client may cause to run the services before Oracle Software installation. You need to remove this service. For remove you just need to stop this service it run temporary and automatically deleted from services.msc window.

4. During running setup you can ignore the OS check

For DB installs:
setup.exe -ignorePrereq -J"-Doracle.install.db.validate.supportedOSCheck=false"

For client installs:
Setup.exe -ignorePrereq -J"-Doracle.install.client.validate.clientSupportedOSCheck=false"
