Hello,

My system was running win 11 pro OS. After re-installation the OS is not upgrading to Pro from home. The system originally was shipped with win 10 home OS, later upgraded to Win 10 Pro.

On entering the license key the error saying

"It looks like the hardware on the device is changed."

 

Can't reinstall Fidelity Active Trader Pro

Fidelity Active Trader Pro and it's shortcut disappeared from my computer. I tried to reinstall it but I get the message "C:\users\desktop\fidelity active trader pro 64.appref.ms is denied" What's the fix? Fidelity's tech reps couldn't solve the problem and suggested I contact M/S. My computer is up to date on updates and PC Matic has Active Trader Pro white listed.

 

Reinstall Win 10 Pro

Hi,

I had Windows 10 pro installed in my laptop, and had to send it for a repair. Once I got it back, retailer has installed Win 10 Home version.

I have linked my Win pro 10 (Ver 1803) to my windows account, prior to sending for repair. I can see that the device is still listed under my name.

Is it possible to reinstall Win 10 pro back in the same laptop? If so, where can I find the activation key? Windows was pre-installed when I purchase it.

Thanks.
