SSIS Error – the path for isserverexec.exe cannot be found

Recently been working with getting multiple SQL Instances on one machine to work. When I uninstalled an old one it affected the latest one. Then all of a sudden my ETL jobs failed. It did not make sense at all seeing as I removed a different instance.

Got the following error when trying to run my ETL jobs or when trying to deploy the jobs:
“the path for isserverexec.exe cannot be found”

Looking for solutions online, they recommend going into the registry. Which didn’t work for me.

I ended up using the install file and running it to add features to an existing connection. And there is was Integration services was not installed for the instance that I was getting the error with.

Installed SSIS on the current instance that needed it and all worked perfectly after that and the jobs ran as perusal.

Hope this helps someone else in the future.
