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?
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
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
