I have the DevExpress Subscription v18.1 and I want to install the v18.2 trial version as I need to test new features. Will the trial version overwrite my current version? Can different multiple versions co-exist on the same computer? In addition, can I use several versions in the same project simultaneously?
Major versions can be installed at the same time and co-exist on the same machine. For instance, the following versions may exist simultaneously:
Please note that you cannot use several major versions in the same project since it may lead to unexpected conflicts between component versions.
Minor versions cannot co-exist on the same machine simultaneously. Minor versions (e.g, v18.2.3 and v18.2.4) are updated automatically, removing previously installed minor versions.
There are many reasons for this, mainly because our components utilize a lot of design-time wizards, project templates, etc., and having multiple minor versions of the same major volume (for example, 18.1.6 and 18.1.7) in the GAC may result in the incorrect operation of these tools, not only because of our components' requirements, but because of .NET infrastructure specifics. (We hit this wall with older versions of our .NET components.) This is why our modern installers always look for other minor versions of a major volume on your machine and remove them completely if found. This makes the installation process smooth and clear.
