I'm trying to install Python-2.1 on Windows, and I keep getting "Corrupt Installation Detected" when I run the installer. [but no other evidence that it's actually corrupt]
You didn't say which flavor of Windows, but should have <wink>. Ditto what it is you're running (the PythonLabs distro? ActiveState's? PythonWare's?).
Known causes for this from the PythonLabs installer include (across various flavors of Windows), in decreasing order of likelihood:
+ Trying to install while logged in to an account with insufficient permissions (try logging in as Adminstrator, if on a version of Windows where that makes sense).
+ Trying to install over a network. Copy the installer to a local disk first.
+ Conflicts with anti-virus software (disable it -- indeed, my Win9x Life got much saner after I wiped Norton AntiVirus from my hard drive).
+ Conflicts with other running programs (like installer splash screens always say, close all other programs).
+ Insufficient memory, disk space, or magic low-level Windows resources.
+ There may or may not be a problem unique to French versions of Windows.
Any of those apply?
