Since there is so far no reply here some further details:
The question regarding RST arose from receiving the info that IAStorUI would not run after the system recovery.
It appeared to me that the system recovery does not seem to install RST but it has such a folder. Also Acer does not show such a driver on their download site:
For the
Acer TravelMate 8572G-564G50Mnkk (64 bit)
SNID: 04100510325
they have the following Intel drivers (Note: Treiber=Driver and the recovery CD was made when the laptop was purchased in Dec 2010)
AHCI Intel SATA AHCI Treiber 9.6.0.1014 10.0 MB 2010/06/21
Chipset Intel Chipset Treiber 9.1.1.1024 2.3 MB 2010/06/21
Turbo Boost Intel Turbo Boost Treiber 6.0.0.1179 40.2 MB 2010/06/21
VGA Intel VGA Treiber 8.15.10.2202 37.9 MB 2011/08/25
Wireless LAN Intel Wireless LAN Treiber 13.2.0.30 128.4 MB 2011/05/18
Therefore, no driver for RST, but the folder is there under "Programs x86" and producing an error message that IAStorUI (which is part of RST) would not run.
Asking Intel they suggested "You can also try our latest generic Intel® Rapid Storage Technology driver at this link:
https://downloadcenter.intel.com/Detail_Desc.aspx?Dwnld..."
I tried then to install the setup.exe, receiving first the message that net 4.5 would not be installed and, after installing it, that the setup could not be made on this platform.
Any suggestion on what could be wrong and how to possibly fix it is welcome.
Thanks.
