"The Company File version is not supported" after upgrading to 2019.4

Just to clarify, the file I posted was supplied to me from MYOB.

Thanks for the followup, Steven, and thanks to mooman79 for prompting the fix.

Same problem here. I suddenly can not make use of a desktop app that needs access to the company file.

It works!!

Great support - TA!

As happy as you are, I'm hesitant to run a random binary added to a post by a user who apparently doesn't have any history in the forums.  Examining the contents, it looks like this is overwriting DbVersionInfo.ProductVersion.  Can somebody from MYOB confirm that this is a valid fix, and that it won't fubar anything moving forward?

Do as you will. I shared your frustration and spent an hour or so to get this file emailed through to me. Thought I would post here to save other people the heart ache. 

I appreciate the effort, I just want to make sure that it's not going to make things complicated down the track, eg updates blocked because DbVersionInfo.ProductVersion is an unexpected value.

I think your only other option is to call MYOB support as I did. I was told it was a known bug affecting the file and the file i posted corrects the issue in the file.

Hi Everyone

AccountRight 2019.5 is an internal build of the AccountRight range (not released to clients). We have noticed that a very small subset of client's data files will be showing that version if taken locally and accessed through the API/Server Edition. 

For those impacted clients, there is a tool available, which can be run to downgrade that client back to 2019.4. We do only recommend running this tool if you are impacted by this situation i.e. you are prompted upon opening with relating to 2019.5 or accessing the file via the local API. The Tool is attached to this post and does need to be unzipped/extracted before running the AccountRight Hot Fix Tool. Do ensure that you have a backup/copy of the myox file before attempting.

Note: The majority of the clients will be unaffected
