View Full Version : This installation package could not be opened.

04-04-2009, 11:33 AM
Greetings all,

I am using a trial version of InstallShield Express 2009.

I am using it as part of a larger install that uses the Intelligent Updater (bootstrapper) whereby I have three packages that I am installing from the web.

When installing from the web, the first package is downloaded by the bootstrapper and I can see the download progress. As soon as it is done downloading a messagebox pops up stating "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."

When I run the same setup.exe program directly on my computer it runs okay. But there is a messagebox that pops up twice to announce "This is an EVALUATION VERSION of InstallShield." which also requires that you click on the OK button.

I am wondering if this extra button (perhaps hidden behind the intelligent updater window) may be causing it not to work as part of the larger install.

Any guidance would be appreciated.
