How to migrate to 64 Bit Theatre Manager

Commencing with Theatre Manager version 10.07.117, when you start up the application, messages may appear to guide you through the process, one step at a time.

If you do not receive a message, you are converted already.

The steps to update are:

  1. Verify your operating system version is 64 bit. TM will check your machine and provide the appropriate message/link for:
    • MacOS: High Sierra or later is best and the upgrade is free. El Capitan or later should work.
    • Windows: Win 10 Pro, server 2012 and server 2016 are best. Windows 8.1 Pro or server 2008R2 are acceptable.
      Note: Win 7, Win 8 Pro and Server 2008R2 (64 bit) should work in the near term. We intend on examining and possibly implementing technologies like transparency (probably by summer 2019) that might mean those need updated by that time (an extended grace period)

      Please make sure to install all Windows Updates as you may get an error that TM cannot run where the real issue is missing updates.

  2. Install 64 Theatre Manager. Once your operating system is 64 bit, TM will check if you are using a 64 bit version of TM.
    • If not, you will be notified and can download the 64 bit installer.
    • Once downloaded, all you need to do is install it using your administrator password using the Installation Instructions
  3. Verify the Pricing Maps you are using. Be sure to read and understand how graphic maps are built using 64 bit Theatre Manager. It is similar to, yet simpler than 32 bit. You only need the SVG maps.


64 bit is available for all Customers

The timeline for updating is by Jan 1, 2019, so there is plenty of time to follow the process above.
You can still use the 32 bit or 64 bit versions of Theatre Manager interchangeably against a common database until the deadline above.

It means you:

  • Should pay particular attention to your currently used graphic maps on the first machine before installing on any other machines.
  • Can restore the 32 bit version on the same machine or reinstall the 64 bit - and TM will continue to work. Your data will compatible, regardless which version you use.
  • Can use any combination of 32 or 64 bit MacOS or Windows on the various workstations in your office
