Can I install multiple versions of a Bentley OpenFlows product on a the same machine? For example V8i and CONNECT Edition.
You cannot have two versions installed on the same machine, except for PondPack (V10 and CONNECT Edition can be installed at the same time). The only way this could be done was if you were running a virtual machine on your computer. Then you could install one version of the product on your computer and the other on the virtual machine.
A copy of the installation folder of a particular version can be stored somewhere and the executable file can be run (such as watergems.exe) to open the product, but some functions may not work properly so we do not officially support this.
It is also worth noting that if you save a model in a newer version, the model cannot be opened in an earlier version. For example a model saved in CONNECT Edition cannot be opened in V8i.
