Adobe Air version 2.5.1.17730 will not uninstall or update.

My computer

AMD Phenom 9150e Quad-core 1.80 GHz with 7 GB memory

Windows Vista Home Premium (64 bit) with Service Pack 2.

NVIDIA GeForce GTS 450

I tried to update Adobe Air.  It downloaded fine.  I click the run button and it showed in the bottom tool box area( minimize.  running mouse over it showed the screen to install), however it will not restore to full screen so I can install.  I have uninstall all adobe programs (reader/flash/shockwave) and they uninstalled fine.  I reinstall same programs and they all installed correctly.  Adobe AIR will not.  I've even tried to delete program without any luck.  I've gone to MicroSoft for  help and no luck.  I've tried all the suggestion here at adobe no luck.  It is affecting other programs on my computer as well.  WHAT CAN I DO??????

It does not give me any error codes.  The best I can tell is it happens with "adobe Air setup"  and I get "Runtime errors"  I am not a program
