Flash is launching cmd.exe. What is -skipARPEntry parameter?

Hello,

I want to understand how this works. I would like to know why Flash would need to launch cmd.exe. I understand that it may be necessary but I would like a confirmation and a technical explanation as to why this is necessary.

This particular commandappears to delete a particular .exe process.  What does the >> NUL at he end of this command mean?

"C:\WINDOWS\system32\cmd.exe" /c del "C:\WINDOWS\system32\Macromed\Temp\{CF184F3E-3E25-4415-AFFA-938D7D8E08CD}\InstallFlashPlayer.exe" >> NUL

Just an additional example of what I see. Just want to know what the parameters are doing or what they mean. Obviously -uninstall is fairly self-explanatory but what of the others.

C:\WINDOWS\SysWOW64\Macromed\Flash\FlashUtil32_24_0_0_186_ActiveX.exe -uninstall activex -msi

What's the difference in Plugin and ActiveX? These examples are also related to the command above.

What is this doing? This is related to the first command listed above (note the same temp file path)

"C:\WINDOWS\system32\Macromed\Temp\{CF184F3E-3E25-4415-AFFA-938D7D8E08CD}\InstallFlashPlayer.exe" -install -skipARPEntry -iv 2 -au 4294967295

Please provide technical explanations if possible or a link to the proper documentation. Much appreciated.

Thanks for the help. If you need anything additional I will try my best to provide you with more information.
