I installed the eval version of installsield express. Now it can't find any of the VFP definition files?

>Unfortuantely the version of Installshield Express which ships

>Ideally you will want to edit the Upgrade table of your MSI database.

>Create a line as follows in the upgrade table.

>In the new row make sure the Upgradecode column is the same as the
>upgrade code for you old apps. Set the VersionMax and VersionMin
>columns to the minimum and maximum version that should be upgraded.
>Set Attributes to 1025 and ActionProperty to OLDPRODUCTS
>
>In the properties table make sure SecureCustomProperties contains
>OLDPRODUCTS.

>You have now told Windows Installer to UNINSTALL your old application. Your product will automatically be uninstalled during the Windows Installer execute sequence. Your upgrade will then be installed.
>
>If you are willing to change how MSIExec is invoked, you can skip changing the upgrade table. You're old application will not be uninstalled however.

>In this instance you can invoke the Windows Installer with
>msiexec /i packagename.msi REINSTALL=all REINSTALLMODE=vomus

>You are telling the installer to Reinstall your product and the "v" signals the installer to use the new package you have instead of the package cached on the
