Changing an installation from 64-bit to 32-bit

Prior to v1.1.3 of Events2HVAC, the software installation on a 64-bit operating system loaded the files as 64-bit code.

Due to some issues with some drivers that can only run on 32-bit systems, the installation program starting at v1.1.3 will only install 32-bit code even on 64-bit operating systems.  On 64-bit systems the 32-bit code will run under the WOW64 system.

Because of this change, if you had previously installed Events2HVAC on a 64-bit PC prior to v1.1.3 and you upgrade the software to a release 1.1.3 or later, you will need to take a few manual steps to make sure your previous settings and license are properly transferred.

Application Folder Changes

The default folder if installed as 64-bit is:

C:\program files\streamside solutions\events2hvac

The default folder for a 32-bit application on a 64-bit system is:

C:\program files (x86)\streamside solutions\events2hvac

You will need to copy the following files from the 64-bit location to the 32-bit location:

  • Events2HVAC.config
  • Events2HVACServer.config
  • License.xml
  • Any *.log files that you want to keep for reference
Copy the files:
  • Create the new 32-bit path:  C:\program files (x86)\streamside solutions\events2hvac
  • Copy the above files into this directory.

Registry Location Changes

The default registry path for 64-bit application is:


The default registry location for a 32-bit installation on a 64-bit operating system is:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Streamside Solutions\Events2HVAC

There is nothing critical to copy from one registry location to another.  These are mostly installer settings from past installations.

Remove 64-Bit Installation

  • Go to Control Panel - Add/Remove Programs to uninstall the existing 64-bit Events2HVAC software.
  • Reboot the PC so that the old service location is completely removed from windows services (not required)

Install the 32-bit Installation

  • Run the Events2HVAC (x86) installation software as you normally would
  • Make sure you select the correct event provider and the device interfaces for your site.
  • Before the setup wizards runs (after you close the installer), copy the files saved from the 64-bit directory above.
  • Run the setup wizard to verify everything is still setup correctly
