You may alreay have done this but assuming you installed the files via the IK Product Mananger and did not installed them manually
Yes. In fact, I've installed everything using IKPM for Total Studio 3.5 MAX Maxgrade without any issues, and all sound for SampleTank 4 Max, but only failed on the one file ST4_MAX_Sound_Library_Update_1_5.zip. I did perform a manual install of this file and it worked without any issues, as suggested by IK support.
I uninstalled and reinstalled IKPM and tried to install the Sounds for SampleTank 4 MAX, same issue.
I have my downloads going to F:\Downloads, which doesn't have a SampleTank 4 folder (not sure why). I have C:\Users\Meerkat\Documents\IK Multimedia\IK Product Manager\SampleTank 4 with nothing under it.
I had to move some stuff around for disk space and I'm sure that I messed something up. Although, I was able to Sounds for Syntronik SAM and SampleTank 4 SE within IKPM just now without any issues.
