I run Window 7 x64, ExifTool 10.02. Default C:\Windows\System32\cmd.exe
When i run exif in cmd with default codepage, which is 437, works fine. But in 65001, which is UTF-8, doesn't work.
Also, when there in %PATH% nothing except exif, exif also crash.
I attached 2 pics showing this.
PS, sorry if my English suck.
I don't really understand your first problem, but your second problem is simply that exiftool requires the more command line tool which it can't find any longer since the path doesn't contain the directory where this command is located. Instead of have a path consisting of just the exiftool directory, it should also contain the standard system directories. I hope this clarifies things a bit.
Running exiftool without arguments brings up the help page using the "more" system utility. You can read the online application documentation if you have problems with this on your system. It should not affect other exiftool commands if this doesn't work.
