Solved: Problem with Public Beta 4.5.1.15

Windows 7 64, Access TI
Previous official version 4.5. worked on this system-
Control center works after public beta update and indicates that everything is ok.

Problem: TI dll does not work at all.
It doesn't show as VSTi in sequencer (Sonar) despite same folder structure as previous install.
It also does no longer work with Savihost wrapper (name error when starting savihost despite renaming savihost.exe correctly to Virus TI.exe)

Anyone else?
Any idea?

There must be something wrong with the Windows 64bit dll.
The new beta version dll was only below 300kb big and did not work.

After reinstalling the original 4.5 release, everything is back to normal, and the dll has around 650kb.

Marc, Timo, whoever?

Arne, thanks a lot: that led me on the right track.

Somehow during the public beta install the 64bit dll got into the 32bit folder, don't know how.
Problem solved now after reinstall.
