Install errors on Win7 MCE 64bit

[incapete]

I've successfully installed MCE LoveFim which launches fine but when I try to authenticate my LoveFilm account it comes up with an error message stating < INVALID APPLICATION Unable to launch "LoveFilm MCE" >

I'm running a fresh install of Win7 Ultimate 64bit.

Does anyone have any ideas on how to get this app working? Thank you!

I have exactly the same issue when installing on Win7 64bit. I have tried this on two machines and both allow the initial authorisation with lovefilm butthen report the 'INVALID APPLICATION Unable to launch' error message once authorisation is granted. Any help with this would be greatly appriciated as this looks to be a great addition to MCE, if I can get it to work.

Hi sorry for the delay. I don't seem to be getting notifications for this thread, and only just saw this issue.

If you get an error message like that, go to Control Panel -> Administrative Tools -> Event Viewer, and then open the folder Applications and Services Logs -> Media Center. All exceptions are logged in there. Cut and paste that and post it to the forum.

Thanks

I have the same issue, when clicking "Set Lovefilm username". Here's the event details.

Thanks in anticipation !

The error message implies that it can't even get the URL to authenticate you, which is very odd. I have added a new version, 1.0.8, which will provide more diagnostics. Try installing that and turning on logging by going in to regedit, and navigating to HKEY_CURRENT_USER\Software\MillieSoft\LoveFilmMCE. Add a new String value called logFile and type the name of a file to log to, e.g. C:\Users\Martin\LoveLog.txt. The file must be in a directory that the local user can write to without elevated privileges (e.g. not C:/Windows). Then re-open LoveFilmMCE and it will write what it is doing to that log file. Send me the file so that I can see more about what is going on.

Thanks

Pob,

what's happening in the code is that it tries to post some data to http://openapi.lovefilm.com/oauth/request_token, and it comes back with an error saying that it is not authorized to do so. That's obviously not what should happen - you are not authorized to GET data from that URL, but you are authorized to post it.

So, what software do you have on your machine or your network which might interfere with this? For example, a proxy server, or an internet gateway, or some odd browser settings?

Can you describe your problem? Sometimes problems look the same on the surface but have small but important differences, so best if we take it from the top when looking at your problem.

Thanks
