Hi Daniel,
Thank you for choosing Windows 8 and giving us an opportunity to assist you.
From your description, I understand Adobe Flash plug in crashes when you try to play you tube videos and now you are unable to install the Adobe Flash player and shock wave on the computer.
Could you answer few questions to understand the issue well:
1. What is the Web browser that
you use?
2. Does this issue occur while installing other programs as well?
3. Was Internet Explorer working fine earlier?
4. Have you made any recent changes on your computer prior to the issue?
Let’s perform these methods and find out the reason behind it.
Method 1:
Try to install the program in Clean boot state.
Clean boot: To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software
conflicts. Here is the link for your reference to perform clean boot.
