I'm installing SP2 on my 2008 R2 servers and it has gone well for the most part. However, I have one machine that is giving me fits.
If I run the SP2 install executable, it unpacks and I see a DOS window flash up and disappear. That's it. The temp directory where the files were unpacked gets deleted.
I run the install on another and copied the unpack directory over, so it wouldn't get deleted. If I run the setup.exe program, the DOS window pops up and disappears again. So I opened an admin command prompt and ran it that way. All that happens is the copyright message is displayed (Microsoft (R) SQL Server 2008 R2 Setup 10.50.4000.00 Copyright (c) Microsoft Corporation. All rights reserved.) and then I am returned to the command prompt.
Setup.exe is not shown as running in task manager after I'm returned to the command prompt. I have admin rights on the box. I'm running this from an admin command window. UAC is disabled. Both the SP, server, and OS are 64 bit. There are no entries in the windows event logs. I cannot find any sort of installation log to troubleshoot (I looked for C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap. There was no directory by that name in the 100 folder.). I cleared the Windows Installer directory (%windir%\installer) and the IE cache. I've rebooted the machine. The Windows Installer service is running. This is the same executable that runs fine on other servers (copied from a central share).
Does anyone have any other ideas? The server is a test server used for evaluating a new product. It only has SQL Server and this other product on it. We use an older version of the product, so I know it works with SQL Server. OS is Windows Server 2008 R2 Standard. It was a new build and I successfully installed SLQ Server 2008 R2 and SQL 2008 R2 SP1 on it when it was built about 2 months ago.
The lack of errors or logs makes troubleshooting this somewhat difficult, to say the least.
