Error 1001. InstallUtilLib.dll, unknown error

[jayshukla]

Here is my scenario: I am working on migrating a 931 extension to version 10. As per the ESRI link, I have made changes and the revised installer and it works fine. When we went for deployment, the user account that we used before (@931 level) comes back with an error. It throws this error: Error 1001. InstallUtilLib.dll, unknown error. With some accounts with higher privileges, it works fine. it seems like there is a permission issue and I want to know what I need to ask from our System admin to resolve this issue.

have an application (extension) that works fine on Windows XP platform. When I run this application on Windows 7 it throws this error. I am not sure what is causing this. I was thinking that it could be due to the fact that .net framework is not installed but I can see all in there. Looking for any ideas to resolve this issue.

Note: this error comes up when I click on a combox box. How can i get past this message box and get to actual error.

Thanks Jay
