Questions about Installer/Builder/Standalone

[Mike Callahan]

I tried this but it did not work:

1. I copied and pasted runTk.py to the top of my script.
2. I ran simple.py to generate a proper Install_xxx.exe
3. I ran the install_xxx.exe and got the tk folder, the xxx.exe and the
support files. The tk folder is at c:\xxx\tk
4. I moved everything into a new test folder on a different machine with the
tk folder under the test folder ie. c:\test\tk.
5. I double click on xxx.exe and nothing happens.

I thought that if I moved the tk folder to the same relative position,
directly under the main folder, and I ran runTk first that my app would use
the tk at c:\test\tk. Is installutils.installCArchive() doing more than
simply unpacking?
