Windows Updates need to be run

After installing the 64 bit version on Windows, you may receive a message that says Theatre Manager cannot start because a component is missing.

While the message says to try re-installing the program, the real issue is that some essential windows updates have not been installed.

We have encountered this on some Windows 8.1 installations that have never been updated. After running and installing all windows updates, TM was able to run.

You can revert back to 32 bit Theatre Manager by downloading it per these instructions if you have insufficient time to run windows updates.
