Since the market link leads here I assume you did the Spotify Controller app.
I just installed the server on Win7 x64 and...there is a LOT wrong with it.
I actually package software for a living, unless you protest I will probably try to put together a PROPER package for the current version of the server software.
Honestly, using a zip file means everything gets tagged as a download from the internet, which means every batch files prompts (or more usually, just flat out fails when called from a batch files). Using a vbscript to create shortcuts is ok, but the shorcut didn't have the working directory set. It points to the controller.bat in the main directory, which calls controller.bat in the server subdirectory, which is redundant and asking for trouble. The batch files it calls will almost never work on Win7 (even 32 bit) and surprised it works in XP, because it calls %~dp0java but the JRE by default doesn't add itself to the PATH variable so the server fails to start 100% of the time (this can be fixed by finding the path to java.exe and setting the shortcut to call java.exe and then the command line (don't forget to set the working directory to the /server folder or it will vomit). So both those batch files are unnecessary and break easily.
I had to go through the install.bat and change the paths from %~dp0 to hardcoded, again you could probably come up with just about anything OTHER than a batch file and it would work, as opposed to the way it is now which...doesn't...
Also for us US users new to the party the example URI in the installer isn't available in the US so no matter what it's broken, I found a Green Day song (Jesus of Suburbia) that works and appears to be available everywhere.
The server is nice, and fast, and for what it is (and the price) works well. Especially for "party mode" of just switching between playlists or "ohhh I really wanna listen to song x right now!"
But the installer as it is...is so broken as to be virtually useless. The only downside to me making a package for this is that everytime you update the software I'd either have to do it again or use something free like, I believe nullsofts installer.
