Installshield renaming of product creates issue with upgrade.

[vinaya...@gmail.com]

Hi all,

I have created setup of my application using installshield 11.
I want to rename my product. But first version of the same product has
been already released.
Now if I try to upgrade the first version with the latest setup which
has different product name, it is giving network error while upgrading.
I think it is because of different names of .msi files in two different
versions. Because installshiled creates .msi file with product name.
Please help me with some workaround.

Thanks and Regards,
Vinayakc
