Browni Computers

 

Start here

 

 

If you have no luck with that open the following folder c:\windows\system32\macromed\flash

 

Look for a file that starts with "FlashUtil9". You may see more than one. Each file has a letter next to it (e.g. FlashUtil9c, FlashUtil9d).

Right click on the one with the letter highest in the alphabet and run as administrator.

Follow the on-screen instructions and that should install the latest version. 

 

That works for the majority of Vista installations, if you still have no success try following Adobes troubleshooting guide here http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_19166
