Error while installing siebel client or tools "OUI-10133: Invalid staging area"

I had a Windows 7 machine (32 bit and 64 bit , both run to the same issue), and tried to install Siebel 8.1.1.0 Developer Web Client (before applying the fix pack 8.1.1.11).

The installer was throwing the following error "OUI-10133: Invalid staging area. There are no top level components for Windows NT, Windows 2000 available for installation in this staging area. " just before the installation is finished.

after lot of experiments i have found that the problem was with the Windows_Image_Creator.exe.

Below are the steps I have done to fix the problem:

1- Go to "$\Siebel_Install_Image\8.1.1.0\Windows\Client\Siebel_Web_Client\Disk1\stage\langs\en " and check if folder has 2 folders "Disk1" and "Translations". If you do NOT find the folder named "Disk1" then continue with this solution otherwise this solution does not apply to you.

2- The problem is that the Windows_Image_Creator.exe did not create the folder called "Disk1" in the previous path mentioned in step1. So we have to fix this by running the windows image creator again to create the client image correctly.

3- Before running the windows image creator, go to where the JAR files are, in my case: "$\Siebel_Install_Image\JAR_8.1.1.11" and look for the two following JAR files:

if issue is coming during client installation 

- SBA_8.1.1.11_Base_Windows_Siebel_Web_Client

- SBA_8.1.1.11_enu_Windows_Siebel_Web_Client

if issue is coming during tools installation 

- SBA_8.1.1.11_Base_Windows_Siebel_Tools

- SBA_8.1.1.11_enu_Windows_Siebel_Tools

The problem was here: the Windows_Image_Creator.exe picked only the Base JAR file to create the client install image and for some reasons it did not include the second JAR file which is the language file enu.

4- So my way to get through this was:

a- Moved the Base JAR file SBA_8.1.1.11_Base_Windows_Siebel_Web_Client away to a different location (ex: to Desktop)

b- Renamed the language enu JAR file from SBA_8.1.1.11_enu_Windows_Siebel_Web_Client to SBA_8.1.1.11_Base_Windows_Siebel_Web_Client

c- Run the Windows_Image_Creator.exe. again to create (fix) the Siebel Web Client install image (DO NOT delete the client image that was created before, this step will only fix the existing image by adding the missing folder Disk1)

d- After the the installer is finished, go back to "$\Siebel_Install_Image\8.1.1.11\Windows\Client\Siebel_Web_Client\Disk1\stage\langs\en" and make sure that now folder has 2 folders "Disk1" and "Translations".

5- Try to install the Client again, and hopefully this time it will work.
