Problem installing a Sony Ericsson PC suite

[Stephanatic]

Hi,

No way to install properly on my pc following Sony Ericsson W900i ... in my PC.
There is a point that comes in pop-up: the version of Windows does not have the latest service pack request. It is better to upgrade your system.
I uninstalled the rest of my pc K750i to reinstall the W900i ... and this pc following the K750i, I can no longer to reinstall ...
I always Windows XP 1 and my pc following my K750i had never posed any problems ..
Is there someone in the room that can help me understand? Thank you.

With SP1, I had the PC Suite K750i and it worked properly.
And this PC following the W900i does not pack2.
Since I uninstalled it and tried to install the W900i I have problems .. .. Some people advise me SP2 bringing yet more restrictions ..
I must add that using 'reg cleaner', I may have manually deleted files (from PC Suite K750i) that I had to leave ... but which ones?

Try reinstalling SP1?
