The recommended way to get both versions running on the same machine is:

1.13 Cross-release compatibility
It is not possible to have multiple versions of QlikView Desktop installed, i.e. the QlikView 11.2
Desktop installer will overwrite a QlikView 10 Desktop installation. However, the QlikView 11.2
Desktop executable file can be copied to any location on the hard drive and run from there without
conflicting with the installed QlikView version.
In order to run multiple versions of QlikView Desktop on a single machine, please follow this
procedure:
1. Uninstall prior version
2. Install QlikView Desktop v11.2
3. Copy the QV.exe file to a new, safe location
4. Uninstall QlikView Desktop v11.2
5. Install prior version
Following this procedure, you end up with a working version 11.2 QV.exe, but the operating system
treats the prior version as your primary version of QlikView.
QlikView 11.2 has a file format compatible with versions 9, 10 and 11.
The QlikView Plug-In client is automatically installed with QlikView Desktop. If the version of either
client is changed, it is recommended to do an uninstall of the previous version before installing another
version. If any of the installations become unstable, they can be corrected by repairing the affected
installation.
QlikView 9 Workbench and QlikView 9 WebParts are not compatible with QlikView 11.2.
