Hi, ive searched around to see if this has already been answered, but i failed.

If you remember, matty helped me fix that ibm laptop and now i installed firefox.2.0 on it, and that was no problem. And i was able to install IE 7 on my dads laptop (xp sp2) With no problem other than how slow the installer was.
On this ibm laptop, the version of xp is sp1.  And everytime i try to install IE 7, i get "IE 7.ene-.exe  (i cant remember the file name) is not  a valid win32 application. When i download IE 7 for other operating systems, i get a different error message "This is for the wrong operating system" Or something like that, again i dont remember it excactly. If you want me to post screenshots i will. So can anyone tell me, what im doing wrong, and if IE 7 is not compatible with xp sp1? Thanks
