asp.net - CutyCapt not able to generate HTTPS web site screenshot when launched from w3wp.exe -

i have updated latest code svn , complie cutycapt qt sdk 4.8. , have static-linked libeay32.dll / ssleay32.dll in same location of binary.

it works fine if launch cutycapt process in command window.

it works fine if launch cutycapt process asp.net (w3wp) capture http web page.

it not work if launch cutycapt process asp.net (w3wp) capture https web page, generates blank image.

i doubted because libeay32.dll / ssleay32.dll dependencies not loaded, copied these 2 dll system32 / syswow64, not resolve problem. monitor process processmonitor, shows me libeay32.dll / ssleay32.dll loaded successfully. so, dependencies not reason.

here c# code launch cutycapt,

using (process process = new process()) {     process.startinfo.filename = ti.exefile;     process.startinfo.errordialog = false;     process.startinfo.createnowindow = true;     process.startinfo.windowstyle = processwindowstyle.hidden;     process.startinfo.workingdirectory = path.getdirectoryname(ti.exefile);     process.startinfo.useshellexecute = false;     process.startinfo.arguments = string.format(@"--min-width=1024 --delay=1500 --javascript=off --auto-load-images=on --plugins=off --java=off --url={0} --out={1}"         , ti.url         , destfile         );     process.start();      process.waitforexit();     process.close(); }  

does knows how allow cutycapt works w3wp?

solution: have resolved problem modifying cutycapt source. idea that, html of url set html webkit.
