No issues here.

You are using current release 4.0.2 and it sounds like you know this but you did point to the ST 4 sounds library path(s), right?

I point to my paths

D:\Music\IK Libs\ST3 libs

D:\Music\IK Libs\ST4 libs

(I completely shortened paths because in a few cases the defaults even in ST 2 were bumping up against the 255 character path limits even an issue for Win 10. I suspect at some point IK will have to re-think DEFAULT paths and file names (I don't use defaults at all)

Double check: if ST3 was installed first, and it probably was, a lot of the ST4 IK SOUND CONTENT installers seem to pick up that OLD ST3 path. If you were just running the IK Installers and merrily clicking away doing the various repetitive steps adn not paying attention a lot of the sounds may have gotten installed, and commingled with ST3 sounds - that also means you have a ST3 and ST4 mess to clean up first.

ST 4 should have had a MASTER library installer - that unpacked and installed "discovered" zip files - the user should not have to manually unzip and install what 100+ files


FWIW Only current known issue (see IK forum) is any ST3 imported libs (like older ST2, Miro Phil. 1, etc.) will not be seen/loadable in ST 4. IK is aware and working that one

good luck
