I am trying to create a package including Crystal Reports in VB6. I get missing files

U2dapp.dll
u2dpost.dll
u2fcr.dll
u2fsepv.dll
u2xml.dll

However these files don't exist on my system. Presume they are part of the Crystal Dependency file.

if i ignore the files, I get 'Set up cannot continue because some files are out of date' on the users machine.

Click OK to Update.

The machine reboots, but I get exactly the same message the next time i run setup.exe.

Any thoughts??
