IE8-64bit - how to get a 32bit back to work flash?

Question: how do I fix the following Errors and down load or get the computer to download Flashplayer?
AC-3100 0x84008503, and a second one when I tried to download flash. telling me I had a corrupted 32-bit something
What I think caused it:
Ok so a while ago I tried IE9-beta and then uninstalled it which led to the IE8-64bit taking over. I now can not access anything that needs Flash player. I also can not access AOL9.5 which for a few days was allowing me to access those programs that needed flashplayer.
What I tried:
Now I have tried to download Aol9.6 and google chrome and firefox to use something other than IE and while I now have Aol,and firefox loaded neither one can find my wireless modem even though I can have it running on IE at the time. I have run spywaredr and Adaware (before I removed it). All of this seemed to start when my Norton subscription ran out. I also tried a cmd: winsosh refresh.

My system:Tech Support Guy System Info Utility version 1.0.0.1

Processor: Pentium(R) Dual-Core CPU T4200 @ 2.00GHz, Intel64 Family 6 Model 23 Stepping 10

Please help... can not afford to bring it somewhere to have it fixed and need it for work. I teach 7th grade.

 

Is this a new laptop? Have you had Flash working previously?
If Flash is already installed, which it doesn't seem like, then uninstall it.
Then try downloading and installing the Flash Player from here:

That's Flash just for IE.
Hope it works

 

the laptop is 1 year old... Also I got Flashplayer "square" to download just a few minutes ago.. it says it is a preview of the 64bit version ... fingers crossed it stays working. still working on other issues.
