The ieshims.dll is not used by the DSM It shows up in the dependency walker because the shell uses that dll if it’s available, but it doesn’t fail if it’s not (it’s not a ‘hard’ requirement).
So your problems have nothing to do with IE8.
On a 64bit Windows system:
WindowssysWow64 contains the 32bit version
Windowssystem32 contains the 64bit version
When an Applications does a loadlibrary on TWAINDSM.dll, Windows will load it from the correct location, the location depends on the Application being 32bit or 64bit.
The only way to use 64bit scanner drivers, is to use a 64bit App that uses TWAINDSM. The only datasources reported by the 64bit DSM, are those located in Windowstwain_64
The log from the DSM might help determine why it hangs during scan. Create and set environment variable TWAINDSM_LOG to the path and name of log file. See earlier post on this thread for more details.
