Solved WIndows Installer not working

[sam49]

Hi I have just reinstalled windows 7 Professional on my hard drive, and now I am reinstalling all my software but I am having problems.

I am logged on as administrator but when I try and install some software I get the message as in the screenshot

These are genuine programs and they were installed on this computer before but will not reinstall now

Can some one help please

PS I am also getting this message as per screenshot when I try to open some folders

Which folder are you trying to open? Screenshot of Device Manager please. Did you install 32 bit by mistake?

 

[sam49]

oh boy I have just checked and yes I have installed the 32 bit version by mistake.

So do I have to reinstall the 64 bit version from scratch again

 

[GokAy]

Yes, there is no upgrade path from 32bit to 64bit.

Ok thank you so much.

I am well annoyed with myself I have spend loads of time and effort and installed all the updates and most of my software.

Well that's a steep learning curve for me
