    Please can you help me download the latest Adobe flash player to Windows Vista Home Premium. I get lots of download offers but every time I try the program goes through its steps, says it has downloaded but it hasn't.

    Thanks, Steve.

    Thanks for the reply. Not getting error messages.Checked out site you suggested. Tried to download manually. No success. I am running a 32- bit system with an Intel R 2140@ 1.6 GHz processor and 1.00GB RAM. Is this a problem?Do I have to also uninstall Adobe reader and AIR as well before trying again?

    Thanks, Steve.

    Wouldn't have thought that was a problem

    you could try uninstalling those, but I am not 100% sure.

    Can you go back to a restore point to a time when your PC was working 100%

    feel free to email me at to try and sort this out
