Title: win32com.client.Dispatch("EA.App") - how to reference 32 bit and 64 bit version?
Post by: roman104 on July 07, 2023, 05:07:10 pm

Hi All
I have installed EA15 and EA 16 64 bits at the same workplace.
I am performing application backup of MS SQL repositories into EAPX files via method
MyProject.ProjectTransfer(SourceFilePath=MySourceString, TargetFilePath= MyDestinationString, LogFilePath=MyLogFile).
Is there any way how to reference 32 bit version and 64 bits version?
I am planning to switch from EAPX to QEA files and I need to have both version of EA  in parallel for some time until I uninstall EA15.
I am looking for the way how I can in script (in my case in python) to reference "ea.app" 32 bits (EA15) and "ea.app" 64 bits (ea16)
Thank YOu
Roman

Hi Roman,

From memory there is no way to differentiate 32-bit from 64-bit, 32-bit and 64-bit have the same version and build numbers.

Can't you get the application exe path name somehow?

Hi Vega
thank You for confirmation of my assumptions. .
But I have another notebook, where there are the same applications EA15 and EA16, 64 bits. On that second notebook is by default starting EA16 OLE server not EA15 OLE object.
I am not aware How I have got this situation. How the windows knows which is default?
I will be forced to uninstall EA 15 and try once again.




Hi Qwerty,
I am afraid, but I could try it, to put isntead "EA.App" reference to physical file, with ole server.
maybe it could be, but I have no experience with it.
Thank You

Hi

As far as I recall, it's the one installed last that takes precedence. Something to do with the way components are created in the Windows Registry file.

Hello Roman,

I have not tested, but maybe you can choose which EA runs with EA.App after running 'EA.exe /register'. This option updates entries in the Windows Registry.

When you want to run EA 15 by using EA.App, run 'C:\(path to EA 15)\EA.exe /register' then use EA.app. When EA 16,  run 'C:\(path to EA 16)\EA.exe /register' then use EA.app.

Hope this works and helps you.

Hi All,
I have found the differences which may cause which version of EA.APP (32, or 64 bits) is launched.
The key is client , python version. If I am using 32 bits version its launch the 32  bits version of EA.app.
In case I run the script via 64 bits version of python, it launches  64 bits version of EA.App.


Thank You very much for Your help.
Roman :)
