changing an existing Aras 12 installation

Hi Mark,

do you use the 'same' installer? Have you tried to use a fresh downloaded or copied version of the installer? It´s probably a registry problem. Maybe copy the copied installer to another folder location, then run the guid thing and try install again.

Most of the time, maybe already a second data base does the job. At least when you don´t do a lot of codetree development.

Hi Angelalp

I used the new installer which bizzarely took me to the old instance

in fact the root problem is errors in .net and iis so the aras application never got the chance to run

thanks for the input

Hi Mark,

do you get an error message? 

I looked at the windows server console and everything is erroring! its a wall of errors there is corruption of dotnet.exe and KERNELBASE.dll

Do you get a error message when trying to start Innovator? These are more easier to identify then the windows messages.

By default installing certain Innovator versions (like 12SP9) kill the server.  Typically you will get Error 503 as in this video:

This error literally kills complete IIS. Your problem sounds similiar.
