I am trying to install the Device Recovery software on Windows 7 Home Premium 64-bit. Towards what appears to be the end of the install, I get "DPInst Result: [-2147483648]" When I click OK on that, it says nothing was installed. I've tried troubleshoot compatability but still get the same result under XP SP2. Any suggestions would be appreciated. I just found out about the memory bug. I will try the erase and reset and then following the other suggestions for using the SL2 until I can get the Device Recovery to work.
