Like other people I appear to have problems with the install on windows 7-64, first and foremost the installer does not recognise the Emacs version that it downloads itself and auto-starts a new emacs download at every time the installer is invoked (looking in a hardcoded path rather than the windows program path perhaps ? eg \program files rather than \program files (x86) ?) .
Also the batch files run at the end of the install do not function properly and appear to be trying to find a folder that is not there
Tested latest stable and development versions downloaded today
Any ideas?
