Express Cache installation error: ecbase.dll file can not be found

I have this problem too. Then, I give it a try again today, Before that I uninstall PerfectDisk 12.5 and installed Diskeeper 2012 instead, update a lot of driver including wlan, nvidia gpu, realtek hd audio, bluetooth. Then today the installation went fine without any problem! In fact, I didn’t use SanDisk ReadyCache software, but I used Asus ExpressCache 1.0.100 on my Asus S46CM.
