There is a dedicated forum for UFT....You might want to move this thread there.
If you are referring to UFT, UFT comes with all the add-ins.
By default, only those addins are installed...if you did not choose advanced option.
If you have license for UFT and require any other add-in like SAP/Oracle/java/.NET....you can re-run the set-up and choose modify...it will take you to add-ins installation.
If you are referring to QTP essentials, this is a scaled down version with support for web add-in only.
More info can be had from
Hope this clarifies
