Failure Installing VS 2008 SP1

I am trying to install VS 2008 on Windows 7 x64 and am running into a fatal exception during the installation. The relevant error message is the following:

C:\Users\jayna\AppData\Local\Temp\Microsoft Visual Studio 2008 SP1\VC_IA64Runtime.exe - Exe installer's log file/hint (%temp%\dd_VC_IA64Runtime*.txt|%temp%..\dd_VC_IA64Runtime*.txt) does not exist or is invalid.

I have found several articles on this, the most promising of which indicates that the remote debugger should be uninstalled. I run into another issue when trying to do this which indicates that there are "invalid characters in the Program Files path".

--------------------------- Microsoft Visual Studio 2008 Remote Debugger (x64) Setup --------------------------- Error 1324.The folder path 'Program Files' contains an invalid character.

Another article suggested turning off Virtual Clone Drive to resolve the latter issue, which i have done to no avail.

As you can see, I'm hitting some dead ends here. Any suggestions or advice would be most appreciated at this point.
