Hello @Fayez Elmassry   thank you for your update. To recap, your update says AWCC was uninstalled and then reinstalled. Hopefully there was a Restart so that the uninstalled process was consolidated before the reinstalled.

Have just visited the Support for Dell G5 5590 page to look at the general AWCC v5.2.91.0 installation requirements. You will have pressed on the [Detect Drivers] button, to detect your service tag and to get your specific installation requirements. We note that the general AWCC requirements are:-  

1. Before AWCC v5.2.91.0 installation: Check your audio driver is v6.0.1.8394 or higher. Download the Dell SupportAssist and let this check for updates, or just install the Realtek High Definition Audio Driver v6.0.8928.1_A03, and then Restart.
2. To install or update the AWCC v5.2.91.0: The Dell G5 shall be connected to both mains power and battery power. It needs all the available power to install and process this very large 630.63 MB update. Do not have any other programs running. Remember to Restart so that installation process can fully complete.
   

If you get prompts to install additional AWCC components, make sure you remain on both mains power and battery power.  

Make sure to set your power plan to High performance also to get extra power and get the operation done faster.

@crimsom All the requirements were met yet it still didn't work. So i'm very confused about what the issue might be

Hi @Fayez Elmassry  Please check the AWCC .exe download file integrity.

1. Go to your Dell Support page, click on AWCC information icon to open the AWCC page, click on View full driver details, scroll down page to arrive at Check Sum values. 
2. Right click on AWCC .exe file, click on CRC SHA to get selection window, click on last entry triangle to open another window with list of Check Sum values. 
3. Compare SHA1 and/or SHA256 of the a) Dell Support Check Sum values, with the b) AWCC .exe file Check Sum values. If identical the download file integrity is confirmed. If not identical the download should be attempted again to get identical Check Sum values.

Ohh. Now I understand,

So the Alienware versions of the command center differ from the G-series laptops command center.

Dell G5 15 5590 Compatible Systems list for AWCC v5.2.91.0, A00 <ADMIN NOTE: Broken link has been removed from this post by Dell>

Hello @Fayez Elmassry 

Is your Dell G5 15 5590 operating system Windows 10 Home x64 or Windows 10 Professional x64? 

Is your user account a Local Account or a Local Account with Admin Privileges when installing Dell updates? 

Thanks for the listing @crimsom.

@crimsom Windows 10 home edition and i'm not sure about the admin privileges but i think so yes. Also the app gets downloaded basically and it opens like a loading screen for 10seconds with the alienware logo then it disappears and nothing happens.

Hi @Fayez Elmassry  thank you for your update. To recap, a) the AWCC download file integrity is confirmed as good to use, and b) Win10 Home Edition 64-bit is good to use with the AWCC 64-bit application. To see the type of user account being used when installing Dell applications, go to Windows Settings and click on Accounts to see one of these icons:- 

Please right click on Taskbar at the bottom of the screen and then click on Task Manager. Look at top of Task Manager window (defaults to Processes tab). With nothing running except your device, the CPU usage should be about 3%. This confirms that the Dell installer and after Restart, running the AWCC application has all of the device resources it requires for successful installation and loading additional applications.
