WebSphere Commerce 7 | Management Center | Not loading from January 12, 2021 | Options to make it work

From January 12, 2021 onwards, everyone are facing issue while opening the Management Center, which was part of WebSphere Commerce 7. It was because Management Center is based on Adobe Flash and Adobe will no longer be supporting Flash Player after December 31, 2020 and Adobe will block Flash content from running in Flash Player beginning January 12, 2021.

For your knowledge,
 - On WebSphere Commerce v7.0, Management Center has been built on LOBTools, which works based on Adode Flash. This WebSphere Commerce 7.0 ended its support on Apr 30, 2020 itself.
 - From HCL Commerce v8.0 onwards, they moved Management Center out of Flash and it works independently like other browser websites
 
HCL was suggested to try few options on this issue, which they published on their blogs,

We tried Option 2 and it worked fine,

Update mms.cfg file related to Adode Flash installation,
EnableAllowList=1     
AutoUpdateDisable=1
EOLUninstallDisable=1    
AllowListPreview=1
AllowListUrlPattern=*://localhost:8000/

Changes for each browser:
a. If you need to use flash with IE/FF
 - Assuming a default Windows installation, Flash player looks for the mms.cfg file in the following system directories or should be inserted in the following directories:
32-bit Windows -> %WINDIR%\System32\Macromed\Flash\mms.cfg
64-bit Windows -> %WINDIR%\SysWow64\Macromed\Flash\mms.cfg
 
b. If you need to use flash with Chrome
 - Google Chrome uses its own version of the mms.cfg file, saved at saved here, where  <Profile> = Default and the System directory has been created since it cannot be found. :
 Windows: %USERNAME%/AppData/Local/Google/Chrome/User Data/<Profile>/Pepper Data/Shock-waver Flash/System
 
Added mms.cfg file for your reference.
