So I uninstalled Acid Pro 8 after buying it because I hated the "modern, sleek and inspiring interface". (LOL. It inspired me to want to flush it down the toilet)
I bought Acid Music Studio 10 instead because it lacked the "modern, sleek and inspiring interface" (it's like the good, old Acid).
I like it much, much better. However, in the product comparisons it says it has 32 and 64 bit versions but the only one I was offered appears to be 32 bit. (I checked with task manager in Windows 10).
