Hello -
I am trying to check if Internet Explorer is opened during my installation and block installation from proceeding further until IE is closed.
I have written a VBScript custom action to check if IE is opened and then display a message. I am calling this CA during on-click event of Install button in ReadytoInstall dialog. But after displaying the message, installation keeps progressing. How do I block the installer from proceeding further until IE is closed.
That is, clicking on Install should do nothing until IE is closed.
Thanks for your time,

you have to set a property in your action to reference in the condition. Example:
| CODE |
function CheckServicesState(hMSI) string szServiceName, szMessage; number nServiceType; begin szServiceName = "Explorer.exe"; LoadStringFromStringTable("MyString", szMessage); ServiceGetServiceState(szServiceName, nServiceType); if (nServiceType = SERVICE_RUNNING)then MessageBox(szMessage, WARNING); MsiSetProperty(hMSI, "ServiceRunning", "1"); else MsiSetProperty(hMSI, "ServiceRunning", "0"); endif; end; |
Then in your condition on the ReadyToInstall dialog
change your condition for end dialog to:
| CODE |
| OutOfNoRbDiskSpace <> 1 AND ServiceRunning <> 1 |
This should prevent the dialog from progressing and allow them to close the app and click Install again. Hope this helps!
** its worth noting the detection code above probably wont actually find internet explorer. But the important tidbit is the MsiSetProperty bit which should still help you. **

Also note my example was installscript. For VBscript i believe it is
| CODE |
Session.Property "MyProperty" = Value |
or something along those lines

Thank you. It worked.
Actually I was trying with wrong condition. something like ServiceRunning = 1 instead of <>. Your suggestion helped me to try this.
