Issue with IsSelfReg table entries
We have an msi and its project file ism file.
In that entries are there in IsSelfReg table.
When we are trying to upgrade with previous version of same msi, we are getting below error because of the above entry.
But it is not coming with fresh install.
Can you suggest anyting other than moving these entries to Registries.

i have had a similar issue in the past, but this was due to the new msi that was installing an updated DLL that had the exact same version and file size as the one its replacing and it caused this error, the only way to get round that issue for us was to remove that file as part of a custom action of the install prior to installing the new files.

What kind of (Windows Installer) upgrade are we talking about?
I recommended you do a major upgrade - have the installer remove the previous version before installing the new version. Yyou will have the least problems using this method and it should eliminate your issue above. You might need to fiddle around in the INSTALLEXEC sequence to make sure its in the right place.
If you don't know what I'm talking about then be careful as you might make your estate worse with a bad MSI!
- Is this a vendor msi or inhouse msi?
