Hi Markus24,
I follow your steps first upgrade to TDP 4.2.1.303 then open file created by TDP 3.6, after that an error ""Exception occurred in other process""come out before let you enter new password in target datasource, if you continue to finish the compare wizard, there is no problem to show original data.
it's obvious that TDP has something wrong to process data but i would like to check if it's related with your error as I was not able to replicate it.
- when you open file, is there a dialog to ask you "Object will now be loaded. Do you want to start comparing immediately?" how do you chose? is there any difference between these two options?
- Have you ever seen this error "Exception occurred in other process"?
Thanks,
Cindy
