Installer has detected that a previous operation did not complete.

Hi all,

I'm getting following error message while installing Information Steward 4.0 SP1.

Installer has detected that a previous operation did not complete. Do you want to resume?'

I guess this is due to the partial install that did not complete previously. I tried deleting the Information Steward folder from Program files and also relevant registry keys but that didn't resolve this issue.

As a last resort, I renamed InstallData folder in C drive but while installing IS it is not detecting already installed BI4 Platform and Data Services. Is there solution for this?? I don't want to corrupt my BI4 Platform and DS installation.

Thanks
