PostgreSQL version: 9.0.4
Operating system: Windows 7 64 bit
Description: The one-click installer failed to unpack
Details:
postgresql-9.0.4-1-windows_x64.exe failed to unpack. I downloaded it for
several times from different location, so it should not be a corrupted
download. When executed, after the postgresql icon displayed at first
disappared, an error message box showed up, said: (In Chinese, my system is
chinese version) "File name, directory name or volume name is invalid."
I'm wondering if it is because my username on my system is in Chinese so it
contains non-ascii charactors, and the when the installer begain to unpack
files, it tried to get temperary directory name, and since the path contains
non-ascii charactor it might not support, it failed and told "File name,
directory name or volume name is invalid."
