How to change display language in Windows 7 Professional SP1?

[XProCraft]

I have a computer that has French language. And I don't want it. I want English on my computer. And I've heard that the display language can only be changed in Windows 7 Ultimate. Is that true? Also, I downloaded a software that can change the display language in Win7 Pro called "Vistalizator" (Downloaded from here) But after I downloaded and installled the MUI then changed the display language to English this message appeared:

And when I restarted my computer to finish the process, I got the black screen of death with only the cursor on it and I got forced to load the safe boot file. Any help?

Hi XproCraft,
Ultimate & Enterprise are the only W7 versions that support additional languages.
There are conflicting reports about the validity of other programmes adding additional languages.
However looking at your systrem specs and Vistalizator, did you run the 32 bit version??

As you have a desktop you should have a set of W7 discs, i would suggest you try a repair install.

Yes. i runned the 32 bit version while making sure that the language pack is also valid, it still doesn't work.
I think the software is having a problem while editing the registration file, that can be edited manually inside "regedit". I have no experience in this kind of stuff so i can do nothing. Please help me because i'm tired of having to use a computer with French language.
