[wpkg-users] Use of a Lock file

[David Davies]

Since you did not create the Pro/ENGINEER installer, you cannot tell it
to create a file that would serve as an indicator of the installation
progress. You might be able to find some file or registry entry that is
only created once the Pro/E installation is complete, and you could look
for that before proceeding.

Within WPKG, you can have install commands check for the existence of a
file before proceeding:

<install cmd='%comspec% /c IF EXIST %TEMP%\somefile.txt runinstaller.exe
/S' />

However, I am aware of no mechanism in WPKG that repeats some command
until it succeeds. So, if you want to try this, I think you're better
off scripting; that significantly expands your flexibility.
