Impressed with MetaX and I thought i'd try MovieLibrary.
Running win7, ultimate, 64bit. TMP, TEMP locations are on drives other than the system (C:) drive. 395GB free on C: i7 CPU with 6GB RAM.
I downloaded the 5.1.2 version via http://www.download.com and tried installing. On first install attempt, I received an error about requiring a minimal level JRE. I then installed both the 32 and 64 bit verions of java and tried to install again. I then received the following installation error: Error opening file for writting. c:\programfiles(x86)\ManDel Dev\MovieLibrary++\MovieLibrary.exe.
