Yes you can install both QTP and Sprinter on the same machine *but*, you have to have matching versions. QTP 11 will work with Sprinter 11. Sprinter 11.5 **will not work** on same machine as QTP 11.

Also if you have to uninstall Sprinter you will also have to uninstall QTP and then re install QTP because the two applications use some of the same files.

Just to also point out, if you wish to utilize Sprinter 11 patch 9, some extra QTP patches are required.

From the add-ins page for Sprinter 11 within ALM 11, you can find the following text with links to the QTP patches:

Available patches:
HP Sprinter 11.00 Patch 9 includes performance and stability improvements, as well as support for Internet Explorer 9, Firefox support through version 10, Storyboard export to PDF and Word, and support for HP ALM 11.00 Quality Pack 3. This patch is cumulative - it includes content from all of the previously released patches. (Released on: February 29, 2012)

Note: If QuickTest Professional 11.00 is installed on the client machine, you must install the following QTP patches before installing this patch:

* QTPNET_00051
