ProWORX 32 returns prompt for Unity installation CD when it is started

Goals and Symptoms

ProWORX 32 returns prompt for inserting the Unity installation CD when it is started.

Also attempts to open the logic editor returns the following message

"Error Obect=frmsearchsetup.frm, (this is in the title bar of the error message box), the error states: Error source
Environment Project Name: ERROR Object = frmsearchsetup.frm Method=Initialize Err=438 Object does not
support this property or method Erl=0 .LastErr=0"

Facts and Changes

This is the result of a corrupted installation where all of the registry settings may not have been properly replaced
or added during the installation or update of ProWORX 32. Some remnant of the Unity software installation could
also be resident in the cache folder (....Local Settings\Temp...) for the user profile. Since the installation routine for
both Unity and ProWORX uses Active-X and some VB components, the execution of a particular VB component
during the start of ProWORX 32 could be causing it to launch the installation routine for Unity. This could typically
occur in any software that did not completely clean out the cache during the installation. (I have seen this occur
with Microsoft Office and the installation of other non-Schneider software.). Failure to clean out the cache could
be due to some registy or security setting in the PC operating system that prevents it from occurrng.

  • Uninstall ProWORX 32
