I had a partial breakthrough on this. While debugging an SL5 app in VS2015 from the local file system, IE11 prompted me to allow untrusted ActiveX content, which it not done since I migrated to the new PC. This made me suspicious it was mainly security and/or ActiveX preventing SL5 apps from running remotely or from the file system, and preventing it silently.
Following some hints I set the IE11 Options > Advanced > Security node > Check the first two "Allow active content" options. This allowed the SL5 apps to run from the local file system. Partial success! I spent almost an hour fiddling with the Options > Security > ActiveX settings, thinking the fix was most like in there, and it probably is, but sadly there are so many combinations and none of them I tried let me run remote SL5 apps. As an experiment I lowered the Trusted Sites level to *Low* security and put the sites containing theSL5 apps in its list. Bingo! They all run without prompts. So I can now debug and run SL5 apps everywhere I need, so long as the remote ones are in the Trusted Sites list, which is only a small bother. So it only took 2 weeks of part time research and frustrating experiments to find these workarounds. *Greg K* On 3 March 2016 at 18:01, Preet Sangha <preetsan...@gmail.com> wrote: > Are there any clues in the process monitor? > On 3/03/2016 11:34 am, "Greg Keogh" <gfke...@gmail.com> wrote: > >> I've tried fiddling with IE11's trusted sites, compatibility settings, >> different versions of the SDK and runtime, adjusting active plugins, >> running VS2015 under different accounts, running IE11 under different >> accounts, creating dummy SL5 projects, adjusting object tag versions, >> comparing Win8 and Win10 behavior ... and more I can't recall. >> >> All I've learned is that there is no problem at all on my old parallel >> Win8 VM with the same software, and I can run remote SL5 apps when I'm the >> local Administrator.
