Something elseI've noticed is that when doing aVTuneprofile, VirtualBox guestinstances sometimes freeze or crash (which never happened before I installed VTune last night). VTune is running on the host operating system.
Notice thoughthat the"pythonhelpers1" is a Python module located here:
C:\Program Files (x86)\Intel\VTune Amplifier XE 2011\lib32\python\pythonhelpers1\__init__.pyc
C:\Program Files (x86)\Intel\VTune Amplifier XE 2011\lib32\python\pythonhelpers1\genhelpers.pyc
VTune apparently can't find this module, nor can it find a amplxe_pythonhelpers_genhelpers_1_3. So, create a "PYTHONPATH" system environment variable containing this:
C:\Program Files (x86)\Intel\VTune Amplifier XE 2011\lib32\python;C:\Program Files (x86)\Intel\VTune Amplifier XE 2011\bin32
You will need to replace "Program Files (x86)" with "Program Files" if you have a 32-bit system.
Now it works! :)
The simplest solution is to restart Visual Studio and avoid opening any Amplifier results, only VTune Amplifier XE results.
If that doesn't work, you might try uninstalling Amplifier, or use the standalone GUI for VTune Amplifier XE.
[Some technical details: The version of python25.dll in Amplifier is not forward compatible with the version of python25.dll using in Amplifier XE. The version from Amplifier XE needs to be loaded first.]
[The solution mentioned elsewhere in this thread may work, but I won't guarantee the product won't break further.]
