Description

When I am trying to install VS2005 SP1 RTM over SP1 Beta, on a 2k3 R2 Ent Machine I get  this error in a popup dialog:
"The installation source for this product is not available. Verify that the source exists and that you can access it"

The setup exists. I don't know what to do furthermore.

I had the same error (The installation source for this product is not available. Verify that the source exists and that you can access it) when I tried to install SP4 for ArcGIS Server.
This helped me to resolve the issue:

Hope it will help someone.

Hello softer1,

You should not need to start vs2005 once before SP1 can install, but it is possible that with the Beta of SP1 installed you corrupted some state that was fixed at launch. Generally, you should completely uninstall SP1 Beta before installing the full SP1. For additional SP1 related help and questions. Please see heath stewart's blog entries: http://blogs.msdn.com/heaths/archive/tags/VS+2005+SP1/default.aspx

I had this issue. When I looked in the event log I found this:

The installation of C:\DOCUME~1\...\LOCALS~1\Temp\ZNWA0\VS80sp1-KB926601-X86-ENU.msp is not permitted due to an error in software restriction policy processing. The object cannot be trusted.

I followed the instructions at this link:

And it no longer gave me the error descibed above.

Just remove the SP1 beta (Add/Remove Programs, check Show Updates) and it'll install just fine.

I had the same problem. I had to completely uninstall vs and reinstall it. After that the service pack installed fine. Not the best solution but I hope it helps someone.
