Hi WeeMeng Soh
Are you using anti-virus software? If so, which one? It's possible the a/v software is interfering with the installation (we recently had a report of Zone Alarm doing this).
Please provide the Adobe_ADM.log and Adobe_GDE.log files saved at C:\Users\<YourUserID>\AppData\Local\Temp\Adobe_ADMLogs. Upload the files to cloud.acrobat.com/send using the instructions at How to share a file using Adobe Document Cloud and post the link to the uploaded files in your reply.
Thank you for posting the log files and confirming the behaviour is reproducible when you disable the a/v software.
I'm not familiar with the error in the log files and will need to send them to the online installer team for review. In the interim, please use the offline installer posted at the bottom of the Installation problems | Flash Player | Windows 7 and earlier page, in the 'Still having problems' section
This is Shefali from Adobe. We verified your case from our end it is working fine for us.
We need more information to debug this issue. Can we have a screen share session with you, so that we can debug more on this?
Could you please revert back with your time zone and preferable timing for screen share session.
We will schedule as per your time.
It will be really helpful for us to avoid any further installation issues.
