Windows 8.1 64 bit issues

I think this is a registry problem. You need to install SH3 from the disc and then you can transfer your data.
If this isn't the problem, then I am in the same boat as Microsoft.
I, like you, have NEVER had any help from Microsoft for any problem.

The installation program (installshield) has failed in the past and because my stable setup is quite complex to recreate exactly how I like it I have copied and compressed the entire lot. Wrote it to a DVD as a data disc and created my own way of installing the game using 7zip instead of installshield. When you install sh3 using the normal way you are decompressing and copying files anyway. It has worked on a vista laptop I still own and this method also works for sh4. The games run flawlessly on the vista laptop too. If you have a large datastick around 8gb or more you can use that instead of a DVD. Obviously for this to work you still need the original discs to perform the first installation and this process was only stable on my xp machine. I have been tinkering around with the files for 7 years or more to see how they interact and which files are responsible for which game features.

The original SH3 installation routine should work just fine with 8.1.

Your complex stable setup may be transfered after the registry is fed.
It may be necessary to chose the exact same installation paths.

Never tried it your way.
