Change Edition of existing isntance?

I have a named instance of SQL Server 2005 Developer Edition. I want to install VS Team System Foundation Server on the same box, but this needs a default instance of Standard or Enterprise edition. I installed the Standard version alongside the existing Developer instance but now I can't start SSIS and without it VSTS Foundation Server won't install.

I have tried to uninstall SSIS and reisntall it from both the Standard Edition and Developer edition media, but it makes no difference, the service still won't start.

Could the SSIS failure be due to having different editions on the same box? If so, is it possible to change the edition of the Developer instance to Standard (or to change them both to Enterprise edition) without having to uninstall and start all over again. The developer instance is used by several team members, so I don't want to have to uninstall it if I can help.

Any ideas anyone?

No. I should not be something like that as different SQL Server 2005 SKUs(Editions) can be installed side by side successfully provided that they have unique instance names. What kind of processor architecture of your machine? If you install 32-bit and 64-bit SQL Server 2005 on an x64 machines side by side, which is also supported, then it is possible that only one version of SSIS works at one time.

Both isntances are 32-bit. Only differnece is that named instance is Developer Edition and default instance is Standard Edition

Having two different editions (Developer and Standard) on the same box should not cause SSIS to be unable to start. Do the event logs have any messages? When you installed the second instance, did you change any of the logon service accounts?

Here is a lengthy thread on SSIS not starting. Can you read through it and see if it applies to your situation?
