Dear Support,
I've just downloaded the latest TMS subscription manager and tried to change the version in the "Downloaded" column. Then I've got "Access violation" error.
Is it the goal to downgrade?
We could not see this here as we do not have this particular situation of old versions. What happens when you try to rename / move files from folder
c:\users<username>\AppData\Local\tmssoftware\TMS Business Core Library and you check if there is still a problem.
If the problem persists, please also let us know what you have in this folder.
