When updating an existing installation, especially if you are using the same main directory as the old installation, it is necessary to ensure that nobody is accessing the old installation in any way. It is not only forbidden for anyone to run cadett ELSA, but it is even out of the question to use the Windows File Explorer to view any of the directories of the installation. Any such access will prevent the installation from being made.

 

In local installations, this is rarely a problem. If you would run into that problem, there is always an easy way out, namely to simply restart your computer.

 

In network installations, the situation might be somewhat more complicated. It is not unusual to run into problems because of this restriction. In some cases it might be difficult to find who the offender (or offenders) is (are). In such cases, it will be necessary to use some force to throw the users out. An easy way of doing that is temporarily removing the share of the directory in which the cadett ELSA main directory is located. When doing so, anybody accessing the installation will be thrown out. The share can then be immediately restored. Please refer to a topic named Possible problems when renaming existing directory.
