I have a clean install of Windows 8 X64. I have installed TIH2013 version 5551. As others have reported explorer either opens very slowly or doesn't open at all. Apparently this is due to some conflict involving Com Surrogate / DLLHOST. I have tried a variety of solutions - one by one to no avail.
I have renamed the " ti_managers_proxy.dll" per one suggestion on the forum. I have disabled the NonStopBackup Service and the and the Sync Agent Service. I have also turned off TibMounterMonitor.exe and TrueImageMonitor.exe and kept them from starting at boot time. I have also kept TIshell64.dll from starting. There are a few more items I could keep from starting using the Autoruns program but I'm starting to get discouraged by having to go through this process. I have no account and have never used the sync service. What else must I do to resolve this issue - short of deinstalling the application which does resolve the issue?
