Regarding Registry entries.

Hi,

We have package our product using Installshield (5.5). the product is component based. When we installed on some machines which had Windows 2000 professional machines, it crashed. But the package installed on some other machines with windows 2000 professinal is working fine. What might be the problem?
Does corruption of registry entries will lead to this of crash? Because, before we install this product, we uninstall its previous version. One more thing, on uninstalling, the components got unregistered, but it was not physically removed from the system.

Could any one of u people help me out.

thanks in advance

regards,
sats:)
