Erro = System.NullReferenceException

Hello community,

Every time I try to start a NEW flow or EDIT an existing flow this error message appears.

I have already reinstalled the PAD, restarted the machine and this error persists.

Does anyone have any ideas?

 

"Message = Object reference not defined for an instance of an object.
Erro = System.NullReferenceException

    Hi, I dont find the link to download the previous version. Could you write me the link, please?

    Thanks in advance. 😉

    Hi @alrofe 

    I basically reached out to Microsoft Support they provided the link to download the software. This was the link that was given to me.
