@Uncle: After searching the Net, it seems that after all the problem lies in your scrrun.dll file...
Please try to (re)register this dll ... Start->Run-> regsvr32 scrrun.dll
Unregistering this DLL here gives the same error message, followed by "Default style not found" message.

Worked a treat! Thanks for your help.
