upgrading sbs 2003 sp1 to R2
I'm trying to upgrade our small business server 2003 w/ sp1 to R2. I already have sp2 for sharepoint installed. I'm also logged in as the built in Administrator. Now when I try to install R2 I get the following error from setup.exe:
"application has generated an exception that could not be handled"
Has anybody seen this before, and is there a fix?
