|hello and thank you for the comment.|
Well, exactly the same installer did work in 2 other WinXP Pro Laptops (with harddisks) and in one of them I can even use the Bluetooth's A2DP feature.
And, yeah I'm able to select a different folder but it doesn't keep installer from asking "Please select a destination folder on your hard drive" and it doesn't go on from that. It's very likely to be about the SSD change, but I might still be misunderstanding the problem.
I've named the CF-PATA setup as SSD for clarity in the title. Believe me it works as a decent SSD, most of the processes work faster and more smoothly than the 5400rpm harddisk.
