How to Uninstall Thingworx Flow 8.5?

Hi,

 

We have installed Thingworx 8.5 with Flow ( ThingWorxFoundationFlowPostgres-8.5.0-x64 ), since it is having some bug internally, we are unable to write any workflow service inside the composer. So we are planning to uninstall it, but we are unable to find any uninstaller for it.

 

Should I remove one by one like erlang,RabbitMQ..etc.,

Or do we have any common uninstaller to do it?

 

Regards,

Janakiraman P

Hi @Janakiraman-P 

 

Recently I faced same problem on my Windows Server 2019 while installing Thingworx Flow 8.5. This is due to registry problem, try to delete registry key.  

 

To delete key,

 

1. Run 'regedit' as administrator

2. Navigate to 'Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson'

3. Delete Ericsson key and its sub key

4. Restart your machine

 

Try to install again. It works for me.

VR

Hi @Janakiraman-P ,

 

Thingworx Flow does not have uninstaller. You have to remove one by one. Before doing that you need to stop Thingworx Flow service and ngnix service.

Hi @Velkumar ,

 

Thanks for your responds,

 

I removed all the services one by one and also cleared relevant data from registry cache and AppData.

 

Now am trying to install flow 8.4.3, while installing it is showing a new error as,

"

FATAL: SystemCallError: windows_service[RabbitMQ] (orchestration::rabbitmq line 99) had an error: SystemCallError: The specified service does not exist as an installed service. - OpenService: The specified service does not exist as an installed service. "

 

 

How could i resolve this?

Hi @Janakiraman-P.

 

Per the earlier post, there is no uninstaller for Flow, but there is an uninstaller for RabbitMQ referenced in the error message.  What procedure did you use for uninstalling RabbitMQ? 

 

Regards.

Hi @slangley ,

 

Am using windows server 2019.

 

I uninstalled Erlang,Thingworx Orchestration and RabbitMQ from control panel. Then deleted all the cache and AppData which are relevent to the above installation.

 

Then I tried to install 8.4 flow, the above mentioned error started coming.

 

Does anything goes wrong with RabbitMQ? / Me?

 

Regards,

Janakiraman P
