What's Wrong?

Claude updated itself to 2.0.12 then 2.0.13 and now when I try to run "claude" I get :

Program 'claude.exe' failed to run: The specified executable is not a valid application for this OS platform.At line:1 char:1
+ claude
+ ~~~~~~.
At line:1 char:1
+ claude
+ ~~~~~~
    + CategoryInfo          : ResourceUnavailable: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : NativeCommandFailed

Looking in the install directory ([UserProfile]\.local\bin there is a claude.exe file that is 0KB in size

I tried installing directly from provided powershell script and get the same result

What Should Happen?

Claude should install correctly and be accessible via "claude" command without error
