I just upgraded to the latest version of get_iplayer for Windows, I am running windows 7 64-bit, when I run web PVR manager I am getting a message when I select PVR RUN telling me: rtmpdump.exe cannot start due to incompatibility with 64-bit versions of windows, please contact software vendor.

I have also tried running rtmpdump.exe from the command prompt with exactly the same result.

Can anybody help?

I don't think you reported the complete error message. I'll assume it also included "Unsupported 16-bit application", which should give you a clue that something is wrong with your system since rtmpdump would never be a 16-bit application. The first thing to try is to check for leftovers in autoexec.nt. See:

/topic...#post-1133

Thanks, DinkyPumpkin for your suggestion, however, Win 7 Pro 64-bit does not have a autoexec.nt file. I have attached an image of the error dialog box for your information. Before I installed the new version of get_iplayer the previous version was working OK, however, if I try and re-instal the previous version now it comes up with the same error box as the latest version.

Any help would be much appreciated.

Many thanks.

I have tried adding get_iplayer directory to the PATH, I have also tried starting RTMPdump directly from the rtmpdump directory, the same error occurs in both cases. I am not sure where to look next.

Adding get_iplayer installation dir to PATH won't help. Needless to say, rtmpdump runs just fine on 64-bit Windows. I have no idea what was messed up on your particular system that would cause rtmpdump to be misidentified as a 16-bit application. Maybe you have a misbehaving anti-virus, though I don't know how that would cause this particular error. get_iplayer obviously doesn't touch any system components, so upgrading or re-installing should be irrelevant. Only you will know what you've done to your system. One person reported this same problem to the mailing list, then claimed to have found a solution. However, when asked she refused to supply that solution, so no further light was shed on the problem. The only other suggestion I can offer is to try some different rtmpdump binaries. One alternative (there are no doubt others floating around):

Many thanks, DinkyPumkin, looks like problem is solved with: https://github.com/K-S-V/Scripts/releases version. Downloading has started without any error reported so far. All I did was unzip and copy the rtmpdump.exe file across to the rtmpdump directory and start Web PVR Manager, bingo!

I much appreciate your help, hope this helps others who might come across a similar problem.

I would recommend trying the zeranoe build first. I've just remembered that the ksv build has problems resuming interrupted downloads, which will bite you sooner or later.
