Software Deployment

The answer is; it would depend.

Ex.
If a file is located in a path existing in the first and last path of the env. variable the first path would be used.
Don't know how Oracle checks the variable but some applications hard-code to check first or last path in the variable.

If the original installation inserts "the source is inserting the environment variable at the begining" then go with that.
Note: if it would be the Path environment variable I would append it instead.

Thanx for the valuable insights...another thing for this Oracle 10g regsvr32.exe has been delivered in C:\ProgramFiles\Oralce\Bin[installdir],i have checked the version of this regsvr32.exe with that present in System32,do we need to delete this regsvr32.exe from our package?

If the file is in the oracle's directory then let it be there.. my guessing is that it's used during installation from the original setup.
If it would have replaced the existing on under the System32 folder then it shouldn't.

well i hav checked the custm actions,at no point it is calling for any dll registration,so is it necessary for us to include this regsvr32.exe?

Was the original installation media an MSI?

the source was an exe and i have made a MSI using Set Up capture,i have used Wise Packaging Tool!!![:D]

Then I'm sure there wouldn't exist a custom action as it cannot replicate the legacy setup with unknown functions.
What I usually do is to run a process monitor (in my case a vbscript) to check which processes the executable is calling which may verify some information.

What happens if you remove the file before starting the application and then launch it... does it seem to work?
I wouldn't bother removing it as it would be removed during uninstall, right?

The process monitor script (wmiProcessMonitor.vbs) I was talking about can be found at:

Just search for "Win32_Process - Instance Creation Event"

Hope that helps in any way

actually i have checkd with older versions of oracle which r 9i,8i both r having regsvr32 in them!!!!!can u suggest me onething..Oracle corporation already knew that regsvr32 exists under system32 which would they deliver it again under program files?[8|]

I have no clue, but does it really matter if it exist in the Oracle folder?
I would just leave it as-is.

[8D] Cheeers mate!!!!!!!!!!
