This is just a simple little post but one which was frustrating for us for a while earlier today. When trying to run setup.exe to install the 10.2.0.4 patchset for Oracle 10g on a Windows XP Pro machine (this may happen on other flavours of Windows, I’m not sure) it pretty much immediately crashed with an error in oui.exe.
After much digging it turns out that the problem is simply that the path from which the setup.exe was ran had a space in it (as it was just on the Desktop so was actually in C:\Documents and Settings\<user>\Desktop. Simply moving the file to a folder with no spaces (e.g C:\temp) fixed the issue and the upgrade proceeded as you would expect.
