Hi, first off, go to your page on mypresonus. This will list things like which version of studio one you have a licence for. Secondly the short answer is no. You need a 64 bit Windows installation to run Studio One v4. Older versions (v3 and v2) have a 32 bit installer but from V4, 32-bit support was dropped. Now for the last part - whomever told you you need a 32 bit windows to run a 32 bit executable has told you lies. Windows 64 bit will run both 32 bit AND 64 bit programs natively, whereas a 32 bit windows installation will ONLY RUN 32 BIT PROGRAMS. As a side note, 32 bit applications are becoming a thing of the past. Its all about multi core processors with core counts of 4, 6, 8, 16 cores/threads. Melodyne 5 only supports 64 bit computers and hosts now. Many Plugin vendors are dropping 32 bit support too. (I buy Computer Music fairly often and all their free plugs have dropped 32 bit distributions). 64- bit computing has been becoming a standard over the past 5 years.
