Hi,
I have to Install PM 2.1 Hotfix 3. In the installation readme is written for install to replace the old file and for uninstall to remove the new file.
Replacement would imo mean to place the new file to the directory and rename it to the old name. But then uninstall would be only remove this modified file (new file with old filename).
Or does it mean: Remove the old file with old name from directory and place new file with new name. But what happens, if multiple different versions of the file (multiple filenames) are placed in this directory?
