Hi all.

While deploying the Web Service, i get the following error:

Any ideas?

Only thing that stands out is "Error setting new DACL for: C:\WINDOWS\Temp"

This could be permissions....can suggest a few house keeping things only - no silver bullet.

Confirm Domain Admins are in local admin group? Confirm that MPSDeployment account is in domain admins (which should be done).  relevant services on web service server are enabled such as IIS, also look at windows installer service and remote registry and that they are not set to disabled. Anything in security event log? (turn auditing on for logon events) .

If you can post more info we might have a better chance of a prognosis....

I have the same problem: current setup (for testing purposes): 1 server as ADC/SQL/MPS. Everyhing works fine except the WebService part.
There are no local admin groups on the AD controller, so I can't set them, MPSDeployment is in domain admin. All services are enabled.
At the time of msi-install there are severall entries in the event log. All are Success Audits, Cat: Directory Service Access, Event 565, User: MPSDeployment.
Even full control for "Everyone" on Windows\Temp does not change anything.

The MPSConsumerWS and ResourceManagerWebClient installs went fine.

MPS on AD?  Never got it working even for test environment.  The problems I experienced were permissions related.  MS advised simply don't put MPS on AD.  
When I get some spare time it'd be a good challenge. But until then - I got nothing.

Well a single server deployment of WbH 4.5 can be done. There are some gotchas one has to be aware of and the error given in this thread is a major showstopper - but can be worked around.

Take a look at my blog post at: http://www.vinodunny.com/blog/post/Fix-for-MSI-Error-1603-in-WbH-MPS-Deployment-on-Single-Server.aspx.

Hope this helps.
