Automated installations for non-admin users on multiple machines

We are trying to deploy Exodus (v.0.8.6.0) to a number of Windows 2000 
(SP4) machines on a domain.  To try to automate the process we have a 
startup script that runs the Exodus installation.  We have run into two 
snags.  First, the installation fails as a normal user due to 
file/registry access privileges.  Second, when we do the install as 
administrator using 'runas' the install works fine.  However, all 
shortcuts go under the administrators account and the user cannot run 
Exodus until the administrator has run it once.  If the user tries to 
run it before the administrator runs it we get the following error message:

"Exodus.exe has generated errors and will be closed by Windows.  You 
will need to restart the program.  An error log is being created." 

I am not sure where that error log is being written but I am assuming 
that it goes back to the file/registry access privileges. 

Is there a way to avoid the need to run the program as admin before 
running it as a normal user? Also, is their a better way to 
automatically deploy Exodus to multiple machines for normal users?

Thanks.
