This problem was reported atempting to run copylocale for specified locales on Window 7 Ultimate 64bit. However, last night I was able to successfully run copylocales with 3.5 on Windows Vista 32bit.
I think this issue may be related to running in a 64bit env... but why would some locales work and others not...
I ended up performing the copylocale on a 32bit workstation and copying over the populated 3.5 sdk to my 64bit unit.
If anyone else has seen/heard of this please let me know, I am still scratching my head :-)
Would be glad to file a bug, however have not been able to reproduce it on other Win 64bit workstations.
I am suspecting that my workstation has become corrupted, recently installed Flex 4 and the AIR for android 2.5 sdk as well. However our production builds are still using 3.5. So as far as having a pristine Win7 Ultimate 64bit workstation, I am probably far from it.
Should I still log the bug?
Helpful hint, run your command prompt as administrator as the typical sdk install folder requires admin permissions to create the folder. I was tripped up by this earlier.
