OK, all data here: The entry is there where you told me. On the main section (after the number): Name: standard REG_SZ data: value not set 1.0 standard REG_SZ Installshield DevStudio Setup kernel win32 standard REG_SZ Path of the file (up to the file) flags standard REG_SZ 0 helpdir same path as win32 to the directory containing the file (path not to the file itself) Is there a reason that the software cant find it? Should I complete helpdir?
