QTP/UFT support tip: QTP and Loadrunner(LR) compatibility.
QTP and LR/Vugen has compatibility issues when they are installed in the same machine since they shared several registry entries and DLLs, therefore is not recommended to have both products in the same machine.
However if you don’t have any other option, then there’s a workaround that you can use in order to have both in the same machine but knowing that this is not supported.
The workaround is to install LR and all its patches first, then install QTP; you have to know that every time you install a patch or upgrade LR, then one of both products might not work correctly, most of the cases is QTP.
Now UFT installation is compatible with LoadRunner installation on the same version, so you can have both UFT 11.5 and LR 11.5 on the same machine with no issues.
