Ronen,
I would just like to further understand why you wish you to install Pulse 3? Is this MyEclipse related – are you attempting to follow instructions from another support post where you have been told to do this – if so, can you please give me a link to that thread?
I would like to mention that MyEclipse does not currently have a 64bit version for Windows (but the 32 bit version will run on 64 bit systems without issue). Also, if you install MyEclipse using our All In One installer, it will also install a copy of Pulse 3 for you.
As you are a MyEclipse customer, I wanted to make sure we understood exactly why you needed just Pulse so we can assist accordingly.
