NEWS: For those with the amplitube 3 DLL error (can't load amplitube 3.vpa):
Here is the answer for my support ticket:
My name is Paul Hudson, I am the Support Manager with IK Multimedia. Sorry to hear of the trouble here with AmpliTube 3. Unfortunately, the issue is that AmpliTube 3 does not support processors which do not support SSE2. If you take a look at our AmpliTube 3 page > System, it states that for Windows, AmpliTube 3 support the following:
Windows® Minimal: Pentium 4 / Athlon 64 processor, 1 GB of RAM, Windows XP, Windows Vista or Windows 7. Suggested: 2.33 GHz Intel Core Duo processor, 2 GB of RAM, Windows XP, Windows Vista or Windows 7. Supported Plug-in formats: VST, RTAS.
SSE2 was not supported in older AMD CPUs, it began supporting with the AMD 64 and above.
Unfortunately, any user running the older AMD will have this issue. The only solution is to use another computer or upgrade the CPU to a newer model that supports SSE2.
This information will be made very clear in an upcoming FAQ as well.
If you have any questions or concerns, please feel free to contact me here.
