Thank you Looks like I'm getting close

I had emptied temp dir before starting setup, and I did copy all files & folders. But it looks rather messy:

{76B6ED0B-E849-4F37-BE58-562E08DA5A21}
bye15F.tmp
isp160.tmp
isp164.tmp
_isdelet.ini
5440.rra
isp168.tmp
ISPackFiles.ini
ispr5544.rra
ispr558a.rra

folder bye15F.tmp/Disk1 contains setup.exe. Should I save this structure of folders? For me it looks like all these folder names were automatically generated. Am I wrong?
