Error 2866: The dialog MsIRMFilesInUse is not allowed to return the argument 6.
When installing ERwin I receive error 2866
This is a windows error, possibly because of the following reasons:
1. There is a running program or programs that would need to be shutdown to allow the installer to complete. The installer is failing when trying to launch the dialog. So Reboot the machine and retry.
2. Also shut off Antivirus and Spyware.
