I see in your app inf file that you've only informed S@H client that you can crunch 5.15 WUs, i bet that your other app inf file didnt look the same or that it simply didn't exist.
If S@H client starts to download other than 5.15 you will get that message that the app required to run for instance 5.17 - 5.20 doesn't exist..
If you edit the file and make alot of differnent posts there pointing 5.17 - 5.20 to the same exe file it will work, but other than that i don't know if that isn't the problem.
And the text "No app version for result: windows_intelx86" sugests me something like if "windows_intelx86" would be necesary instead of "setiathome_enhanced"? Or is it some issue related to Boinc's attempts to better support 64-bit platform?
...the app_info.xml file for the anonymous platform. Berkeley have added a <platform> parameter. If it's not there, you get that error.The fix is to add the appropriate line for your <platform> after the <version_num> line(s), like:...<version_num>512</version_num><platform>x86_64-pc-linux-gnu</platform>...
BTW, no idea whether this solves my problem, I'm offline 'till the evening.
