Oracle Installer:[INS-13001] Environment does not meet minimum requirements

To prevent this dialog box from appearing, do the following:

1. Right click on the setup.exe for the Oracle 11g 32-bit client, and select Properties.
2. Select the Compatibility tab, and set the Compatibility mode to Windows 7. Click OK to close the Properties tab.
3. Double click setup.exe to install the client.

its awful oracle installer:

[INS-13001]

I got it as I used MY_PC as NETBIOS name instead of MYPC (Underscore is bad for it..)

Can be an historical reason.. but message is obscure.

i was also getting this error, remove oracle folder from

C:\Program Files (x86)\Oracle\Inventory

and

C:\Program Files\Oracle\Inventory

Also remove all component of oracle other version (which you had already in your system).

Go to services and remove all oracle component and delete old client from

C:\app\username\product\11.2.0\client_1\

To make @Raghavendra's answer more specific:

Once you've downloaded 2 zip files,

copy ALL the contents of "win64_11gR2_database_2of2.zip -> Database -> Stage -> Components" folder to "win64_11gR2_database_1of2.zip -> Database -> Stage -> Components" folder.

You'll still get the same warning, however, the installation will run completely without generating any errors.
