Problem:

When trying to add an option to our Net Express installation, we continually receive the message - 'unable to load c:\\supportdir\\xinstaln.dll' as we try to install a new option. Where is the DLL xinstaln

used?

Resolution:

This installation process uses this module as a part of its processing. The customer was using the CD labeled 'Studio for Mainframe Migration'. For Windows XP Pro, if he went to the Windows Control Panel

'Add/Remove Programs', then 'Change', he could select the desired option. For Windows Vista it is slightly different in this area: go to 'Programs and Features', then 'Change'.

Because the new releases of Net Express and Mainframe Express use the Microsoft Installer, one cannot re-insert the CD to add/remove options. Instead, one must use the Windows interface via the Control Panel.
