I've posted about this nonsensical issue before. As the source link quoted in that post is now dead and the issue continues with the latest version of WLinstaller.exe, here's the msi source for direct download. It installs fine on Windows Server 2008 (x64) and Windows Server 2003 (32 bit x86). Not sure if it installs on XP Professional x64 as I haven't tried it, it should though.
And while we're at it, here are the other files (msi sources):
Positively no support or warranty.
Keefe Dunn: Thanks for the MSI release. I'm a little bit curious. Did you compile these files yourself or you just found them else where?
Alan: Didn't work for me :( Server 2003 SP2. Tried double-clicking the MSI file and nothing happened. Any ideas? Thanks
Alan: Quick update, it DID work, but very quickly and silently. I had a progress bar that appeared for a few seconds, then nothing. I assumed it hadn't worked, but when I checked the Programs menu, there it was. Hope this is useful to someone!
Yang: Thank you for your MSI file. I intalled it on Windows 2003 Standard Edition SP2.
