Rick,
Thank you for the suggestion. I also do not use a scanner (at least not on this system). I have no idea how/why this version of the twain driver was installed, and therefore, do not know what driver I need to update.
In the meantime, following your suggestion, I renamed the file. PVD now starts without an error message and I did not see any errors logged in the
Event Viewer. I will keep an eye out for any errors that might pop-up related to this (I doubt there will be any).
FYI: Renaming the file proved difficult. I ended up finding a solution at
http://www.experts-exchange.com/Microsoft/Hardware/Q_24082861.html Guymar had a hard time as well and eventually found a solution somewhere else. His solution was:
Solution Part 1:
Update drivers: go to relevant download section of your vendor, get them. Then go to device manager and delete current drivers (ticking the box removing them). Install/unpack vendor drivers and reboot.
Solution part 2:
Manual rename (or delete) both TWAIN.DLL and TWUNK_16.EXE
- Log on with an admiistrator user account (*)
- Go to start menu, accessories, right-klick on command prompt and "run as administrator"
- Type: takeown /f c:\windows\twain.dll
- Type: icacls c:\windows\twain.dll /grant %USERNAME%:f
- Type: takeown /f c:\windows\twunk_16.exe
- Type: icacls c:\windows\twunk_16.exe /grant %USERNAME%:f
- Type: ren twain.dll twain.dll.bak
- Type: ren twunk_16.exe twunk_16.exe.bak
*Note: If your username contains a space it will not work!! "John Doe" will have to create a user John or use the administrator user (if activated).
