Salon Maid Software vb6stkit.dll NOT A VALID WIN IMAGE

Setup fails with a 'vb6stkit.dll is not a valid Windows image' error
This is a documented Microsoft Windows bug. Here are some suggestions for addressing it:
On the target computer, search for a copy of your application's .cab file(s) in the Windows folder (or Winnt folder on NT). If found, delete the .cab file(s). Setup places the .cab file(s) in the Windows or Winnt folder and removes them at the end of a successful Setup. However, if the installation program exits abnormally, the .cab files may be left on the system. (In Space Watch pro v4 the CAB file is named 'swatch.CAB')
In the Windows\Temp folder (or the folder specified by the TEMP environment variable on NT), look for a subfolder named Msftqws.pdw. If found, delete the subfolder. (In Space Watch pro v4 this may also be a subfolder called 'Space Watch pro 4')
On the target computer, locate the following files. If any of these files have a size of 0 bytes, delete the file: \Windows\System\Vb6stkit.dll (or \Winnt\System32\Vb6stkit.dll), \Windows\St6unst.exe (or \Winnt\St6unst.exe)
Run Setup again.
