bug, Git, Windows XP, uninstallation

Dear, Git mailing list.

Sorry, if I've sent this message to wrong address, I actually don't
know, where I should send it.

I have a problem with Uninstalling Git for Windows. For installation
I've used this url:
http://code.google.com/p/msysgit/downloads/detail?name=Git-1.7.7.1-preview20111027.exe&can=3&q=

During installation I haven't changed any settings (all was keeped default).
My OS is Windows XP Professional, Russian.
I've tried to reinstall and then uninstall it again - same error.
There error during uninstallation is on the picture here:

Thank you.

Best regards,
Napadovskiy Vyacheslav.
