I am running Windows 7 SP1 and received error 0101-1007-4032 when trying to upgrade to PlayMemories Home.
I did three things and the upgrade installation worked to completion. I am not sure if any of these steps were unnecessary.
1.) Ctrl Alt Dlt and started Windows Task Manager. I went into "Processes" and killed the process PMBVolumeWatcher.exe
2.) I went to the "Control Panel" and then to "Windows Firewall" and disconnected both "Home or work (private) networks" and "Public networks"
3.) I stopped my virus software
Tried the PMHome_5100DL.exe installation I downloaded, and the installation worked to completion. I now have upgraded successfully to Ver. 5.1.00.12260
Then I restarted the Windows Firewall to the default settings, and restarted my virus software.
