Activex Web deployement fails

Question

Hi I have this Dot net dll(user control) in C#, which does not do anything Special, I have created a setup (.msi ) for the dll. Then i created a cab using cabarc (cabarc.exe N Test.cab test.dll test.inf) test.dll is my dot net dll.

The cab is not a signed cab.

Here is the test.inf file.

[version] signature="$CHICAGO$" AdvancedINF=2.0 [Setup Hooks] hook1=hook1

[hook1] run=msiexec.exe /i "%EXTRACT_DIR%\Setup.msi" /qn

In my environment, it works, i.e. the cab extracts automatically(in any client system in the network), and installs the user control and displays in web page. But outside my office, people have complained that it shows to be installing, but nothing happens afterwards, ie. the control does not actually install.

What could be the reasons?

Thanks
