Solved Installed wrong version of W7

[fstr]

I've had a week of the perfect storm of problems with my multi PC setup! But without boring everyone with the details, I reinstalled win7 home premium, recovered my setup key from a backup after recovering part of the backup from WHS, only to realize the key is for professional, not home premium!

So basically I installed the wrong version of Win7 and it wont allow me to enter the key saying rightly that I'm entering a key to the wrong product.
I also attempted to do an anytime upgrade but that fails without message. I think it is failing because the installed product is not registered yet.

At this point the last thing I want to do is a reinstall because I just finished a weeks worth of work to get the fresh install back to the state I need it in.

What is my best choice here? Can I do a repair install with Professional without losing anything?

If you have sp1 installed, make sure Windows updates are up date.

No install files needed.
Only the Upgrade key is need.
Anytime upgrade only adds-on the Programs & Features from version to version.

Hello fstr, welcome to Seven Forums!


Have a look at this tutorial at the link below, it says Vista but the principal is the same and be sure to post back with any further questions you may have and to keep us informed.

Updates are up to date but SP1 is NOT installed. Further I followed the guides on the anytime upgrade without luck

First set a System Restore Point - Create

Type regedit in Start Search box, rightclick result to Run as Admin, change the two Registry Keys exactly as shown below to trick the installer into running a same-version Repair Install which is always allowed.

SOLVED;
In a last attempt to avoid a repair or upgrade install, I installed sp1 and all the subsequent updates. At that point I did a selective (msconfig) restart and the anytime upgrade worked
Thanks for all the help!
