Program tries to re-install when opening

I am running a reservation program in a restaurant.  Win XP.
Up until a few days ago all was OK.  Now when they try to start the server, it tries to install an earlier version, which isn't even on the PC.
Unfortunately the server holds the data so I can't do much while the restaurant is open, as the office PC runs as a client. It runs OK as all it does is read the data off the server
I have attached photos to show what is happening.
Have to keep clicking on Cancel to stop the process.  If it won't let me I have to use Task Manager to stop the app.

Does this happen immediately when the server is started and Windows begins to run?
nobusCommented:
run msconfig, and check if the installer is in the startup list - then disable it
otherwise, use regseeker for seeking thru the registry for all RESERVIT entries, and look for the installer - you can delete the key there

***it's Always wise to have a backup of data, and Registry before changing anything
